the Unimesh Realism kit should work if he still sells it. As long as the material zones are the same you should be able to use it for any character. I've acctually even modded mine for characters not originally supported by just adding the required material zones to the scripts.

Used here on the Grey's

These are all the same default texture. I just modded the materials and the sliders for color.

 Face-Off doesn't seem to mind, but I can't distribute them of course.
