This also adds a ton of strength, and requires the same size stock to machine from.

I've looked at these gearbox designs before, and I wasn't able to see how it benefited the strength of the gearbox at all. If you could be more specific about how that improves the gearbox strength, that would be really helpful.

The top one is mounted in a weaker configuration because of the orientation of the mounting screws.

As far as I can tell, the top CIM on the WCP 3 CIM DS gearbox is mounted in the same configuration.
