Wow, Mixmaster looks excellent there, well done! But this really solidifies that Demolisher is WAY to tiny to work well. I really wonder what it would look like if you went the following route, though: Repaint Long Haul into Overload and make him the lower torso (the kibble on the arm could be positioned next to Mixmaster to form that panel look), take Voyager Long Haul for the right leg, and use TWO Rampage figures for the left leg, one red and one yellow (or both yellow with different colors in the robot mode). Yes, Overload wouldn't look accurate that way, but if you're really bothered by it then it shouldn't be too hard to make him an articulated dumptruck with the way his kibble is arranged.
