So, I'm trying to make over the Townies with different looks and all. However, I do want to keep most of the the body shape that they have originally.
I have tried MCCC copy-paste face to the original sim or copy-paste body appearance to the new sim, however when I age up the sim it turns out they revert to their old face/body shape, and I can't retain the change even when I copy-paste it to the other lifestages.
I really hope there's a way that I could genetically copy ONLY the face or body appearance. (Copy genetics in MCCC copies them entirely), so yeah-

The image below shows how YA Travis has the changed face, but Adult Travis reverts back. Aswell as YA Bob with the changed body, but Adult Bob reverts back. I've also tried this with a birthday cake but the results are the same.
