Facegen is good at making 3D likenesses of faces, albeit at a much higher price than Poser, and probably needing a degree of expertise to get a good resemblance. There's a good reason that you see very few "digital clones" around the galleries, and it isn't the threat of legal action; this stuff is hard. If you want a complete body likeness, then I don't know of an off-the-shelf solution. I assume your budget isn't unlimited.
