I was looking at the game and character viewer. The viewer is lacking in many areas but that got me thinking. The face sculptor in Riften will let you change basic appearance options but would it be possible to add a "Corruption Sculptor" ? She would give you options similar to in CoC. Different skin colors, eye colors, horns. These would probably be the easiest.
For a more advanced version, she could give you goo-hair/body, futa penis, height, pregnacy/distended belly, and some of the other "unique" options from CoC.
The idea I have is to take your CoC character's stats from the appearance page and bring it manually into skyrim.
Please post any comments/advice you may have.
