I've seen more than a couple military display aircraft, USS Midway, that featured the markings of one pilot and crew they wished to pay tribute to on one side of the aircraft and then the other side featured a different pilot and crew.
Nothing to say you cannot have a split personality painted tank...
Just a matter of deciding where to make the split.
Even seen a few RC cars that the paint job used a tear away effect revealing a different scheme beneath with top peeling away. The 3D effect and skills to make it come alive are a bit more challenging.
