I'm trying to figure out how to build a "Scion of the Monkey King" character.  Basically, to be consistent with the lore, he should be an expert shapeshifter first and foremost.  Other powers that would make sense are channelling air and water, and an item of power (either one of the three remaining strands of the hair from the monkey king, or the monkey king's staff). 

I'm having trouble figuring out what powers I can give the item of power and shift around with modular abilities while staying within the rules.  I realize most of it is the GM's call, so I want to get as many opinions as I can.

For example, basically I want to build him like this:

[+1] Human Form
[-7] Modular Abilities
[+1] Item of Power: Monkey King's Hair
[-4] True Shapeshifting

So that he can fit into a submerged game and still be fairly effective.  Obviously I'm sketchy as to whether true shapeshifting can be given to an item of power.  It makes perfect sense in the lore though (his hair can become a clone which can shapeshift into any form) but whether it makes sense in the Dresdenverse is more important.

And as for modular abilities, my only real question is whether I can give one of his forms [-2] Channelling or [-3] Evocation.  Of course, if I can't, I can always just give a form [-2] Breath Weapon, but the ability to do more than a weapon2 attack with the elements makes more sense with the legend. 

Thanks for the input.
