>>9974013They already made a Hi-Metal VF-19 before and it required pretty minimal partsforming.
iirc they're just a fill-in for the back of the thighs and I think the top of the head is replaced, and the hands.
This was 10 years ago.
I imagine they've evolved the design process enough so that if they were to tackle it today they would do it with even less or none parts forming at all.
