I read back through that thread and saw that adding a new model means players without it can't join.
Anyhow, here are some female skins I found (from http://www.quaketerminus.com/tools/250Quake1Skins.zip ). Alot of them would work for cyborg/soldier/wasteland warrior.
I think alot of these are clan skins. And for QuakeWorld. I don't think there's any format difference, though.
badbabe2.pcx - Wasteland Warrior

ammowman.pcx - Cyborg

CRACKORE.jpg -

cutie.pcx - no idea - Quake Soldier? Cyborg? (she kinda looks like a female Terminator)

deathead.pcx - female deity?


q3phobos.bmp - was phobox a female in q3? There were several doom skins in the pack (above) which are relatively easy to feminize. In fact, are these the colors quake sets aside for pants and shirt -- to be modified with the color command?

tf_medic.pcx - Turn one of these into a female nurse? (cleric)

ironman.pcx - alternate cyborg (or android), easily feminized? Again, is this using the team color range?

victoria.pcx - terrible job on a spicegirl skin. included only for completeness.

dmnatrix2.pcx - this one needs more clothes (which is why you don't see it here), but could be a time traveler? fighter?
ninja - the face is hidden on the male ninja skin, so just accessorize or something (maybe female eyes).
Really any female skin should wear a helmet, or big hair, like CRACKORE.pcx since the head is almost a box. And for that matter, she should be wearing armor. What might be fun is a model where you can change your hair color in-game.
You could always take the CRACKORE head and paste it onto other skins. Hehe.
What about high-res skins? Seems like those would be easier to make.
I can zip these up separately. I'll see if I can find more. Anyone else wanna help?
