One problem with geometry switching (which is a very clever concept!) is that you need to do all (body) morphs twice because of the difference in vertex count.

 

And the problem is?

 

 

Actually, hip morphs (that are NOT related to genetalia) tend to be general shaping morphs rather than  "detail" morphs. It would take about 30 seconds to transfer those kind of hip morphs from one figure to the other using Dimension3D's "Morph Cloth" program.

I'd rather stay in my lane than lay in my stain!
