Nice morph, by the way! And I agree that working on the low-res version when making morphs is much preferable.

I just did a little test on Alyson's face and was able to convert a low-res morph to the high-res mesh by subdividing the mesh and then correcting the vertex order. I'll try a full-body morph next to see if this works without problems for all parts of the mesh.
