Do you think that the the Endgame Star Lord body work?
I honestly don't think so, but I can't say for sure. If my memory is correct, the Star Lord body has the same torso and pelvis as the Bane/Ganghood body with a longer neck but skinnier arms. So if you're looking for something to buff up your Superman, I don't think the Star Lord body will do it for you. If you were to give it a try, the Sideshow belt will most likely not fit. I had to put two belts together for it it to fit the Man of Steel body's waist. The Ganghood body could be an alternative b/c it doesn't have such a large neck, but you'll still need to attach the belt in the back somehow. You'll still only get a 90degree elbow bend, but it'll have larger arms than the sideshow figure
