Ah yes, that seems pretty similar to what I had in mind, with the extra twist that it would transform from one figure to another. So I think my version would be somewhat easier to get working. I've only skimmed your description, so obviously I would have missed all the interesting details. But I'll definitely get back to it if I end up attempting something like that myself.

Yes, Antonia comes with my original layout plus the one MikeJ made with more experience and better tools, and of course the V3 mapping you've mentioned.
