What I am saying is that your weight right now is potentially
lower than reasonable. As you remove so much material, the gearbox becomes less rigid, and stuff will deflect away from each other under load. The CIM mounting is especially concerning as the moment applied by the mass of the motor will tend to bend the pinions away from the cluster gear, weakening both of them.
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. You could still have a heavily lightened gearbox, with just more material and better motor support. You would probably even have a net weight loss if you faced the gears and drilled some holes in them well below the root of the teeth in addition to adding material to the gearbox.
