You're spot on with our thinking, but note that the plates are mostly the same because the CIM-side plate uses a 7/8" OD (FR6) bearing on the output shaft rather than the 1.125" (FR8) bearing on the output plate side. Otherwise, there are no differences between the plates, although we had considered tapping the screw hole in the CIM-side plate to elimnate the nuts.

The "design" is really more or less a copy of what we've observed in the Cheesy Poofs' gearbox designs. We wanted to start simple with a single speed gearbox, then move forward at a comfortable pace to determine what works best for us.
