Yea. You might actually be better off buying HL2 or orange box for PC, buying GMOD, and going that way--though it will still require modelling and animations and all that to be done for truly custom stuff. Course it does a lot of stuff that...well, I'm not so sure we should talk about out in the open.

Anyhow, yeah, I think there is a mod that has a female form to Revan's Robes. Look around.
