While I don't want to ever have to buy another MP Optimus, I just had a thought about how an MP Optimus could be done to look like the animation model.

MP-10 while generally more accurate than MP-1 his chest just doesn't look right and his legs have the bulge of his fenders. The fenders would be an easy fix, make them slide inward to make them flush with the rest of the leg. As for the chest, well why not just simply do a fake windshield? We already have a fake grill, so why not just make the entire front of the torso fake truck parts that looks far more cartoon accurate?
