The overlapped bumpers could be bent beyond allowable dimensions up, down, or out, so even if it's legal at inspection it could incur a penalty during match play. If your intent is to distribute impact along two sides of the chassis, some corner bracing connecting two bumper segments above/below the frame should accomplish this. Also, could you build four L-shaped bumper modules to cover half a side, around a corner, and halfway down the next side with some bracing around the corner? Last year we had two U-shaped bumper modules, one for the left and one for the right.
