Considered using a Mc clutch handle directly on the selector lever? Sequential transmission gearboxes rarely need to be shifted using the clutch, simply applying pressure to the preload the lever while letting off the accelerator will cause it to skip up or down a gear. Given your low input torque, you're barely going to be loading the gears as it is under full power, so damaging the gearbox from shifting like that isn't a worry.
