the Denarians wouldn't have become the Denarians if they weren't very VERY evil
Not that I necessarily think that any of the Denarians could be called even remotely 'good', but do you happen to have meaningful backing for this claim?
If that were the case, one would think that the Prince of Hell would have selected himself.
The angels (not demons) who became Denarians did so to allow themselves to meaningfully interact with the mortal world. That most of them wished such access in order to negatively impact human life is not indicative of the intent of ALL the angels who found themselves in such a position.
Christianity teaches that there is nothing that can put a person beyond redemption, so I assume that would apply to the Fallen, as well. However, redemption requires repentence, and I think it's highly unlikely that any of the Fallen would repent, having become set in their ways since existence was young. What we see of Lasciel (or at least, her shadow) does seem to indicate that such a thing might be possible, but (a) Lash is not Lasciel, and (b) any apparent act of repentence is likely to be cover for a betrayal -- after all, the thirty coins are the thirty pieces of silver which paid for Jesus' betrayal by Judas.
because they want to rule instead of God.
You mean "because they want neither to be imprisoned for all eternity, nor to be subservient to a being they feel has betrayed them in favour of His 'younger children', ie. mankind".
The methods they have chosen, certainly, are not in the best interests of mankind, but then, they were here, first, and it wasn't the Fallen that set this course of action, but rather had a dichotomous ultimatum set for them. They just responded with 'option C'.
FWIW, WoJ
However, all is not status quo, as SmF shows us the definite possibility that the "Prince of f***ing Darkness" threw in on the side of the Denarians. It may be possible that Lucifer is either working a deal with them or is not as much punishing them as may have been believed. We'll see.
I've basically chosen to not paint the Denarians in a sympathetic light (at least not as a group). It's a personal choice, because I love the Denarians as bad guys, and I want them to be bad.
That being said, if you want to go the sympathetic route, I think you could get real mileage out of a Denarian who is seeking redemption, or simply regretful about the path that has to be taken to achieve their goals.
I suppose I just don't see a necessary disconnect between 'sympathetic light' and 'bad guys'. That 'sympathetic light' might be limited a bit when you're talking about an entity that's planning what will, coincidentally, result in the cataclysmic destruction of human society, but I find 'they're doing evil because they're evil' to be rather less engrossing.
I was going to say I agree on the "evil for evil's sake" statement, since what the Denarians want in my Dresdenverse is evil primarily to humanity and certain forces of Good (big G), and probably perfectly reasonable to incredibly powerful beings from the beginning of time. My point focuses more on the "Denarian agenda" as evil, rather than the individuals. I think we're arguing semantics, really.
To address the OP's original point, I personally wouldn't have a "good Denarian," but I think a ton of fun could be had with a Denarian who isn't straight up cackling, kitten-eating evil, but is instead behaving in a way that is at least, on the surface, being good, with a much more complicated reason.
So, yes, I guess you could have a "goodish Denarian" anyway.
What were we talking about again?
... Incidentally, this makes me want to start a topic about Evil for Evil's Sake in reference to certain entities that essentially Are What They Are.
Just because you have a positive refresh level doesn't mean you're 'non-evil', it just means that you have choice. And among the options such choice affords you is Evil. And, as a result of having that choice, get even less sympathy if you take those options than a being that is evil because being evil is simply a part of their nature.
Interesting semi-side note, there is nothing in the Bible about angels getting redemption. That bit is strictly for the humans, who were created with freedom of choice.
It'll be a harrowing journey from there to redemption, but what's a PC without angst and long background arcs?

------
Background: Son of rural farmers, raised in southern Illinois on a soybean farm. The farm eventually went under and was bought by an agricultural corporation. The family lost everything and ended up living poor in Chicago. Though he was intelligent, he did poorly in school due to discipline and anger issues. He eventually dropped out of school and went to work as a mechanic. It wasn't long before his talent fixing motorcycles go him involved with the Outlaws MC "one-percenter" outlaw motorcycle gang, where his instinct with mechanical things, impressive strength and durability, and disregard for rules served him well.
"I Can Do Bad By Myself"
Rising Conflict: Descended into an orgy of violence, sex, and drugs, becoming so vicious he was called Mad Wrench (for his trademark of beating offenders with a 2 ft. wrench and his ability to fix his constantly breaking down bike) and placed into the SS, the Outlaw MC's squad of killers and enforcers. It also served to handle any "wierd stuff" the gang would run into, masking it behind the other violence regularly committed by them. During a conflict with RCVs, his natural ferocity and rage were noticed by the captain of the SS, Lil'Satan. He was taken as Lil'Satan's protege and eventually inducted into the Red Skulls, a secret society supposedly dedicated to destroying supernatural threats, but truly serving as Lil'Satan's personal loyalists. As part of his induction in the Red Skulls, he was granted the token of membership - a tarnished silver coin.
"Mad Wrench is Mad With A Wrench"
First Story: Too independent to be submerged under the Fallen Guziel, he was still heavily influenced, like being permanently affected by supernatural PCP. Over the course of several years, he led a band of the SS in cleaning out a nest of RCV (connected to the ones mentioned previously) who had infiltrated the Chicago Outfit (mafia). He truly came into his own, the knowledge of Guziel and the power of the Fallen allowing him to demolish the RCV infestation.
"Knowledge Of Hell At My Command"
Guest Star: Preacher-Man 10 years passed, and Wrench became the 2nd in command of the SS, he and Lil'Satan ruling their own personal feifdom within the Outlaws. Lil'Satan implemented his plan, attempting to take over the mainstream Outlaws, starting with the assassination of their leadership, but Preacher-Man (a fellow Outlaw, but deeply faithful) interfered, the power of his Faith staggering the Fallen. Fully himself for the first time in many years, Wrench fled, finding himself in the poor, rundown neighborhood of his childhood, at his elderly parents' door. His parents were terrified of him, and his rage flared, ending in their deaths. Stricken, broken, he raged against his own downfall and the Fallen in his mind, who for the briefest of moments, expressed sorrow. Holy Man arrived with a few members of the SS; Wrench begged forgiveness, vowing to earn redemption. Rather than cast aside the coin, he seize\ds upon the brief moment of remorse, determined to redeem not only himself, but Guziel as well.
"Long, Hard Road"
Guest Star Redux: Smiley Wrench and Preach systematically set about destroying the Red Skull members of the Outlaw MC, aided by certain in-the-know members. Their pursuit of Lil'Satan took them to St. Louis, where the last of the Red Skulls were slain with the help of a former SS biker and RCV Infected, Smiley. Lil'Satan's coin was encased in concrete and sank beneath the Mississippi. Rather than return to the main club, Wrench, Preach, and Smiley received permission to open a new chapter, which Wrench dedicated to hunting down the supernatural (and sometimes mundane) predators. He hopes to do enough good to wash the blood from his hands, but he's still an Outlaw at heart, loyal to the only family he has left.
"O.F.F.O - Outlaw Forever, Forever Outlaw"
Interesting character. First off, a minor point: "The Catch: Swords of the Cross" isn't a Catch, since Swords of the Cross already satisfy every Catch. You should be taking the standard Catch of Denarians, which is "Blessed swords, holy water, faith magic, that sort of thing."
YS 185 - "If it is bypassed by something only one or two people in the world have access to or could produce (like a Sword of the Cross), you get nothing." +0
Same page - "If knowledge of the Catch requires access to specific research material that could be restricted(like a wizard's library), you get a +1." +1 (Since you could find out the Swords of the Cross are designed for anti-Denarianism with access to the proper information).
A Sword of the Cross does not satisfy every Catch unless a fate point it spent. If it is the Catch for a Toughness/Recovery power, then it requires no fate point spent to satisfy that Catch, any more than a fate point is required for a Sword of the Cross to satisfy a Catch that is holy items, etc.
Another thing you might want to consider is that your background makes it very clear that your character is very strong-willed, so much so that he is able to hold his ground in a battle of wills against his Fallen. Yet your Conviction is 'Good' and your Discipline is 'Fair'. I think that at least one of these should be significantly higher to represent your strength of will (and Discipline is probably the better choice).
I think that your big problem is going to be that if your GM handles your Denarian correctly, you will be (rightfully) compelled by your high concept at all of the most story-appropriate yet inconvenient times, and assuming your GM does so at the right times (ie, mostly at times when accepting the compel would be very troublesome), you will often have a shortage Fate with which to buy off the compel (assuming you have any at all). By this, I mean that if your GM compels you to kick every puppy you see, then you will end up with a lot of terrified puppies and a pile of Fate to spend on the Important Stuff. But if your GM waits until a key battle against your Nemesis, when your resources are nearly expended, then offers a Fate point and points out that the innocent little girl hiding in the corner would make a wonderful shield to protect you against those sprays of machine-gun fire...
All in all, I think you might be better off considering battling against your Fallen's shadow, rather than the Fallen itself. Perhaps your character pulled a Dresden, and has hidden his coin out of reach, and figures that he'll take on the Shadow first, then if successful they can confront the Fallen 'together' (possibly by 'corrupting' the Fallen with the redemption of the Shadow)?
Regardless of what you decide, have fun with the character!
And it came to pass when the children of men had multiplied that in those days were born unto them beautiful and comely daughters. And the angels, the children of the heaven, saw and lusted after them, and said to one another: 'Come, let us choose us wives from among the children of men and beget us children.' And Semjaza, who was their leader, said unto them: 'I fear ye will not indeed agree to do this deed, and I alone shall have to pay the penalty of a great sin.' And they all answered him and said: 'Let us all swear an oath, and all bind ourselves by mutual imprecations not to abandon this plan but to do this thing.' Then sware they all together and bound themselves by mutual imprecations upon it. And they were in all two hundred; who descended in the days of Jared on the summit of Mount Hermon, and they called it Mount Hermon, because they had sworn and bound themselves by mutual imprecations upon it. And these are the names of their leaders: Samlazaz, their leader, Araklba, Rameel, Kokablel, Tamlel, Ramlel, Danel, Ezeqeel, Baraqijal, Asael, Armaros, Batarel, Ananel, Zaqiel, Samsapeel, Satarel, Turel, Jomjael, Sariel. These are their chiefs of tens.
And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them, and they taught them charms and enchantments, and the cutting of roots, and made them acquainted with plants. And they became pregnant, and they bare great giants, whose height was three thousand ells: Who consumed all the acquisitions of men. And when men could no longer sustain them, the giants turned against them and devoured mankind. And they began to sin against birds, and beasts, and reptiles, and fish, and to devour one another's flesh, and drink the blood. Then the earth laid accusation against the lawless ones.
I would have to say that "Fallen" implies making AT LEAST one bad choice.
Interesting character. First off, a minor point: "The Catch: Swords of the Cross" isn't a Catch, since Swords of the Cross already satisfy every Catch. You should be taking the standard Catch of Denarians, which is "Blessed swords, holy water, faith magic, that sort of thing."
The appropriate costing of such a Catch, let alone whether such a Catch is appropriate in the first place, is a point of significant contention. Tread carefully.
