Here you go. I simply added your Aux channel to the one from
bbird's original nude skin. When he said he had eliminated as much of the "skirt" as he possibly could, he meant it. You've seen for yourself what happens if you try to clip off a little more - there's no leg underneath (and that includes all those little spots - you need those or your character will have "holes").

I don't know why the filesize is so much smaller. If it were me, I'd take the Aux channel from this one and replace the Aux channel in your original and save that. I'm always suspicious of data loss with these compressed formats.
I also took the "liberty" of re-extending the front piece to its original extent - take it from an objective observer, it looks better. The other way is too abrupt. The front should be triangular like the back.
You also want to do some blending where the legs join the hips (the newly visible area). Otherwise, it looks pretty darn good.
