I don't know if anyone still plays this game, but an archive of Skindex had a link to a Yahoo group with a few skins and meshes in it:

They are .nifs... I wonder...
How I loved that game!
IIRC from the NifSkope forums, the format was a bit different, so I don't think it'd work out of the box. Worth a try, though, if someone has a copy.
The characters seem to be divided up into several .nif files, so doing a body transplant is out of the question. When I feel better (hopefully soon), I'll see about doing individual transplants to some meshes. If, however, someone who knows what they are doing wants to go ahead, please do.
Update:
Copying the pieces to Taskmaster seems to cause some of the vertices to spring out at funny angles.
