If you make your low poly figure from the regular one and do not affect the scale, and leave enough head polys to do the job, The Taylor should be able to reproduce the morphs, or at least as much as the mesh allows. The Taylor cannot know that is clothing and what is not, only can know if the groups line up. The other choice is to reduce polys on everything but the head. Since the head has the most polys, this will cost you.
