The swap will work in robot mode, but since the three are different cars (Cliffjumper is a Porsche 944, Bumblebee a VW Beetle and Bumblejumper a Mazda 323), the arms are slightly different shapes, as the vehicles are of different shapes. While Hubcap has some retooling in vehicle mode, it affects the rear bumper & spoiler, not the running boards (arms).
