I've seen systems like that, also with just pegs that come out to stabilize, and another that drops down like a center stand. The clutch/shift I'm working on replaces the left end of the bar, clutch works as normal, but whole grip/end rotates like a throttle to shift. Right leg is reliable enough, usually only pain, so I'm not concerned with the rear brake.
