Hi again!

I saw that Phil C's WW2  now has support for the free character "K", Maybe you can ask him if he could support this character too?
Or if maybe the creator of Crossdresser?

That would solve a part of the clothing issue, also Dimension 3D has a program called second skin (not second skin textures) that makes good bases for pants and sweaters.

Unfortunately my own modelling skills are limited.
