Nice vid! Man this figure feels like it's almost exactly what Hasbro represents to me. Incrementally they'll eventually creep up on a well designed figure, but even at their best they still massively drop the ball in obvious ways. Your mod helps make their bad decisions have less impact, but they just constantly fail on ball joints where it matters. It's like it's on purpose. Like your mod looks insanely unhinged from the body, but that's entirely because of Hasbro's dumb idea of how neck articulation works.
Also the hip range out to the side is completely artificially limited on almost every ML figure with a limited range. It's not even the sculpt colliding, it's literally that the cutout in the thigh doesn't go high enough. That's it. Boil it, pop it, Dremel the slot higher, you get 90° on almost every one. It's embarrassing tbh.
