I keep wondering about how this approach can be composed, vs just doing a single replacement. Example: replace person a head in this video with person b (current examples), make composed person more tan, swap hair on composed person with this other person c hair, add muscles, change shirt with this other shirt, etc, etc. It really seems like the same type of operation reapplied repeatedly. Could be powerful character editor type functionality.
