If you want good nude models you need to do head transplants to the bikini trainer model, change the skin texture to match the characters you want, resize the boobs and body, make sure the armature and bones weight are correct and check if the parent/child hierarchy of the bones are correct.
And that's just the beginning, if you want removable clothes then it's going to take an insane amount of work to just prevent them to clip through the body and make the body fluids like semen or sweat not to look like shinny Play-Doh.
