The texverts for the vertices marked in the image are being successfully split.  With any luck, a 2D smoothing routine can pull the seams close enough to the correct polys to permit easy manual cleanup of the UV's.  I'm not sure a script alone can achieve perfection with this, but it may be able to get pretty close, providing a good head start for a re-mapping.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
