So long as you're fine with a fear monger who either glamers for black fullplate and wears a white featureless mask or glamers a scholar's robe and wears glasses as a lieutenant, sure. The first form is reserved for frontlines fighting whereas the second is essentially the strategist (whose scholarly robes just so happen to feel very solid and chain-like).
EDIT: I've got a build that carries me to level 20 now. Never knew that I'd find something that would match Ira's theme so well, but nevertheless I'll be taking levels in Master of Masks. The poor BAB and d6 HD make me sad, but good progressions in Ref and Will as well as the amazing utility of the masks makes it a solid choice. Plus, it ends up working well with the idea of wearing a mask as an intimidate tool. So all in all it looks like this:

17: Master of Masks 4
18: Master of Masks 5
19: Master of Masks 6
Uncanny Trickster's required to get perform as a class skill for Master of Masks (fortunately it grants progression in previous class levels) and I end up bumping back swift action demoralizes to level 11 (12 with the LA considered), but it works. EWMaster for some delicious x2s to Str bonuses for wielding a bastard sword in two hands (this is a grey area - it can be wielded as a martial weapon in two hands, but I took the EWP to specifically be able to wield it in one hand... so here's where I'm questioning it's validity), Warshaper 1 for natural weapons on the go and immunities to stunning and critical hits (pity I won't be taking this awesome PrC any further).
Still can't understand why someone would take the other Trick-happy PrC over Uncanny Trickster. Even the BAB gain is questionable, seeing as Uncanny Trickster grants class progression on top of what it gives.

I feel like Yoshimitsu now.
