The hex output is the hard part. The GEM line doesn't have hex output, only 1/2 cylindrical. We twisted the output steel shafts on the GEM boxes this past year with our arm... Granted, we were putting a dynamic ~25lb load on the end of a 8ft lever... but still. Also, you can't put two CIMs on one GEM.

You might want to look at doing something really silly with a drivetrain gearbox and connecting it to a RAW box. That could also result in stripping the worm gear on the RAW box though... we had some experience with that too this past year.

Seriously, the AM folks were running away from us towards the end of CMP this year.
