...what if you offered a skin development kit and allowed the contributors to paint/create skins to submit to the devs? I bet you could get 200 submissions and 10 usable skins easily. (sorry, I have seen your Devaintart accounts, and the truly great are few and far between).
A skin is probably a diffuse, bump, transparency, and reflection/glossiness map set, right? Maybe a layer for tattoos and makeup?
I bet the character creator beta could be used to preview them as well.
Just a thought.
