That wouldn't fix the fact that it is still cantilevered. There would need to be a supporting plate on the other side of the gear to reduce the kinds of loads a cantilevered gear sees vs a non cantilevered one.

It would reduce the torsional load on the bearing to nearly zero. A dead shaft rigidly mounted to the gearbox plate can handle high loads that are cantilevered half an inch or less. The bearing moves to the same plane as the gear, much like the gears engaged by the dog/balls in the shifting stage.
