I do have a small request for a change, feel free to ignore it but you seem to take my observations throughout this thread starting a year ago with some consideration (boob topology, eye topology, face morphs in body, split morph, head injection, UDIM etc), many of those we were on the same page... I'm not sure how much of a PITA it would be but I don't think it would have a significant impact on UVs at all, if any. At least from my experience. It might be too much to copy over the morphs yet again though...

More edge loops in the breasts.

As it is large breasts with undercut and gravity/sag will be difficult without SubD morphs. You probably have a preference for petite, as shown by most of your stuff, as do I in general, but it would be helpful for character.
