I think we may have something here.  The process can be seriously optimized, but I've just tested comparing Vicky 1 and Antonia using a closest vertex method, more or less as I mentioned above.

The attached image is Antonia wearing the Vicky Monkey full face morph, without any cleanup.  It looks like a good transfer.  No cleanup!  No mess from screening materials or having verts correlate incorrectly.  The only problem I can really see is the eyelashes, which took influence from the brow.

It helped a great deal to compare the heads with both mouths open.  Luckily Antonia's "Mouth Open" morph cooperates well with Vicky's "Yell".

I'll keep testing, but it looks like this could be the foundation of much more effective morph transfer than is used by TDMT.
