Here's what I don't get. Lately, it seems like most of the BAF's parts are interchangeable. Iron Monger and Mandroid parts fit each other and I'm pretty sure they fit Ultimate Green Goblin too. So why don't the regular figures have matching ball joints and stuff? I picked up a second Marvel Now Cap yesterday because I want another Mandroid. I was thinking of using the movie style spare head to make an unmasked version. I had to sand the ball joint down for an hour and a half in order to get the head to fit. I think it looks decent, but what the heck? Shouldn't these heads be able to be swapped? Am I crazy thinking this?
