I don't see how that would work but I've never tried it. Just by description, I don't see it working well for artists that use 3D painting to texture, since painting in 3D space and pojection painting both remove a lot of stretching even if the uvs are stretched in 2d space. So the polys you've warped in the UV map to accomodate the stretching on the 3D model will wind up being stretched anyway once you start posing the model.

And until people get over the idea of using a T-pose, shoulders are always going to look like crap in poser, whether they are raised above the head or down at the sides. It doesn't make sense to me why this pose is being clung to for a feature like walk designer that is used by a mere fraction of poser users, and this somehow justifies bad modeling techniques. The excuse that it makes clothing easier to model is just lazy, and continues to make clothing - especially for male figures - look like poser 4 plastic instead of actual clothing. 

Its rather ironic - imo - that poser is geared towards the amatuer market, but makes everything else for content creators 2 or 3 times more complicated than it should be, or is in just about all the other software out there.
