Part of the problem with Apollo suits were the shifting CG because of the "rucksack" loose suspension of the Backpack. Which is one reason the current EMU has a hard latching Backpack.

What I found amusing about the article was how graduate students were relearning stuff suit designers "learned" already and this will help design new suits that are right now not funded. We will spend a small fortune on this student learning nonsense and never make a serious Lunar Suit doing it.

Larry Kuznetz proposed a method to do both with a whole series of Universities on board. But, of course that suit making education plan wasn't funded and this nonsense is. This isn't to say these student aren't doing something "important". But to use a metaphor ... only it is to a dead end they're driving!
