I made a program that can highres-ify a figure at selected faces. Not sure if it can help here, but it can be used to create highres-hips, at least ;). Morphs and textures do still work after subdivision. Should work on any figure, on any body parts. 

The figures in the picture are subdivided v4 (at the right place just for this thread ;), on the right with the v4male FBM applied.

Are there commercial high-res hips yet? Worth providing one ;) ?
