[Help] How should I arrange my folders for skin textures?

[Goregonzola]

I greet you!

Here's the situation: I have a character, which has a dynamicly changic hair texture, depending on his current Sanity level. You can see his current folder structure on the first picture. Wolemorm is his default skin, wolemorm 1,2 and 3 are for his three Sanity stages. The numbered folders contain his whole texture package, the only difference between them in the hair texture.

The second picture shows his hair-changing function.

Now, I would like to add him one or two skins, but I'm not sure how the file arrangement should look like. These skins would also have three Sanity stage hairstyles.

How should I approach this?
