Can't you accomplish that now simply by removing the transparent area from the Delete Group? The issue, I suppose, is that the Delete Group won't line up perfectly with the borders of the hole. Mind you, that's only a problem if you're working with a part of the clothing where some of the lower layer's vertices would be outside the upper layer--and if the inner layer is always inside the outer layer, you don't need the "Hide" option (or the Delete Group) in the first place.
In other words, I think the real problem (or at least, a real problem) may be that you need to move part of the lower object, not just display it, because clothes underneath other clothes typically get compressed (heck, even flesh under clothes often gets compressed). A couple of years ago, I tried to figure out a way to do this, and I think it's doable in principle, but it struck me as being too complicated to be worth the effort.
