I like the idea in panel two IN THEORY, at least. The way I'd run between shops in some games makes me think I'd get sick of morphing in unique ways before entering every store. I do like the idea of benefiting from knowing things unique to NPCs you're interacting with, however.
I'm actually more interested in panel three, as I liked faction disguises in Fallout New Vegas, and would like to see disguise systems in more games.
