Well, I didn't find what I was looking for, but thanks very much for pointing me to that site. It wasn't one I'd heard of. There's some interesting stuff there.
I have, yeah (fantastic site). There are a couple there that I could probably tweak, but I was really hoping for an open jacket mesh rather than a painted on affair. I have just exactly the mesh I want on the basic Maxis-type body, but I don't know enough about meshing (read: anything) to be able to convert it.
