Some of the listed gearboxes come with auto shift, which would also work.
But many of them require a break in power for the change.
That means a clutch, which would be a good thing to completely disconnect the alternator and aircon (on the drive side), from the engine.

All this ads weight, so your power to weight ratio goes down.
Less or more than you save..??
Fact of the matter is no-one has tried this, so until it is tried; we don't know.
