I'm pretty sure that would be a manual manipulation of the UV map.
E.g. Unwrap + texture a model (Make sure the textures expand beyond each UV segment). When you come to unwrap another, use the texture as a background -> Try and get the appropriate pieces in the right place.

Nothing is impossible, it's just a matter of determination and probability.
