While the chassis design is heavy, it hasn't been lightened yet like you said. You were planning on making it from folded sheet metal? What lead you to that decision?
The CIM coupling probably would end up going. To clarify the frame is made of 1" aluminum bar. and the pods are sheetmetal. So the pods are the only thing that can be lightened by holes without sacrificing strength.

Concerning the pods sheetmetal design: the fundamental and key design tradeoff with the pod is between making the traction and mec wheels in the pods as far apart as possible (so as to decrease the amount the pods need to turn to get to the mec mode) and leaving room in the for other stuff between the pods. Because sheetmetal is so thin, it allowed me get support on both sides of the wheels in the pod while still keeping the wheels as close to the outside as possible.
