I took a quick glance of the modding guide (wikia) but couldn't find any info on modding UI elements or textures in general..so here i am.

(In the games current state) Is there a way to add/modify the faces, hairstyles or clothes?

I'm kinda buggered that everyone looks like they are long lost cousins with a person "just down the road" and wanted to take a shot at adding a few more hairstyles to start with..
