I don't think any RPG has had that level of customization before. There should be 3 levels. Hair, Face, and Facial Hair. All with the ability to change color. Facial hair is nothing but adding a layer to a texture, and from my hanging out on modding forums, the engine does that already. Color changes are easy, just do one texture and spend like 2 minutes altering the colors for the different choices. 5 heads, 5 hairstyles(plus no hair), and 3 facial hair options (beard, mustache, both) and for males you have like 90 different options for what your character looks like, not counting hair/skin color. And if someone leaked the model format to the modding community you could have much more options too (hint hint)
