No, actually. The gears are heavily "dished" out on the other side, in order to keep those components to a single lathe process. There's practically no weight I can save by removing materials, only adding material.

I like the CIM mounts. That's a very compact way to do it.
The advantage it has over the toughbox is custom ratio, massively lighter, more stylish, more precise, and better bragging rights.

I'm not really a fan of the same 4 bolts holding the gearbox together, the motors on and the gearbox to whatever structure it is mounted to. No matter what, that is going to make assembly and mounting a much bigger pain that it needs to be. I'll agree it cuts down on parts and weight, but I don't think it's worth it.
It would be a bit of a pain to assemble. However, depending on what kind of drive system that it would mate to, two of the mounting bolts may be countersunk. That would aid a bit in assembly.
