Been thinking about this for weeks, but never really got around to it until today. The slot in the top of Mirage's scoop is almost the right size to hold the rectangle peg of his gun. You can't shave the peg down, because you need it to store the gun in the alt mode. So I took a knife and cut away minescule portions of the slot on the top until it fit. Now I can stow his gun in the robot mode!
