Nice design, of course I always advocate that you build and test.

I am hanging the CIM motor off 1/4" plates and think your design will be OK. If you include a mount to the frame of the robot close to the CIM you will definitely have enough support.

As for stopping and shifting with the current spacing....depending on the ratios the chance that both sets of gears will have teeth lined up is slim. This would prevent the shift from occuring. Designs with the shift dog have broken themselves when a "neutral" is not included and the shift is done on the fly. (It may have been JVN who told this story )
