There's no reason to lighten a gearbox so aggressively when you have all that extra material in your gears that serves so much less function than the material you've removed from the gearbox.

I don't see how the top motor is mounted less securely than the top motor of the WCP 3 CIM DS gearbox. In this design the plate is thinner, but the upper standoffs are closer to the CIM.

If I was going to lighten the gears, I would lighten them as much as reasonable too, but that is a different story.
