I've done a morph off of Mass Effect's characters, but no skin textures or anything else; the likeness was close enough but also different enough not to be an exact duplicate.  It helps if you want one of those, to use an actual person as a reference.  Unconciously you'll also add characteristics into it that take the model not just past the copyright infringement area, but a bit more believeable as well.

 

Not to mention the morph wasn't a saleable item, and I've never made money off of it in any art print either.
