Received QuickKick and he does work pretty well for a more muscular comic-esque basketball Remy. The hands that come with Gambit have longer pegs than QK's arm sockets allow for so they will have to be trimmed a bit. The wrist cuffs that come on QK are NOT removable so Gambit's cuffs will not work on it unless you grind down the tips of the forearms, or repaint them like Gambit's cuffs that he comes with (likely the route I'll go).
QuickKick's pants can have the pattern on the hips removed if you want a Gambit that just rolled out of bed or looking like he's been training in the gym, they're more or less just sweatpants, he comes with a built in belt but if anyone knows a GI Joe overlay for a pelvis that's straight black and looks like it could be sweatpants, by all means let me know.
This custom will take some effort, but the skin tone matches pretty well, the head pops on the peg without issue and isn't loose, so that's "half the battle" as the Joe's like to say.
