Unicornst: that is indeed geometry switching.
Did some research, and I'd better not use it. Reason is that the amount of morph data will go through the roof - for each variant the cr2 needs a full set of morphs, and since it is rather high poly, it would get extremely big (tens of megabytes). Separate parts don't suffer from that kind of morph bloat.
And since I'm going to put ERC in everything, you won't have to dial in each and every morph for each and every item: just change the morph setting on V4.2 and all conformed items will automatically adjust themselves.
A Python script that'll magnetize all conformed items to V4.2 in one click might be useful though. I'll put it in the package.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
