@odf,

I just thought about it for a few minutes...
You do realize that all the seams changed, right?
There was never any hope of making any of the new mapping "fit" with the old mapping. That's largely why I did it. I just started out on it for my own purposes, knowing what works best in the programs I use, and I didn't like where the seams were.
I mean no offense by that, but my intent was to make an optimized 3D painting version, where the seam location is a huge thing and it's especially important to have even and proportional UVs throughout as best as possible while not sacrificing resolution.

If I were to go about making a map for the lo res version I would probably do so in the fashion one would do for a game or an animation and map it in SUB-D and place it all in one 0-1 space, with nothing overlapping.
