It looks like you could cut out the center on a lathe, ream the inner bore of the sprag clutch to fit, attach and weld the splined section to the overrunning clutch, then weld the clutch (perfectly, with a jig and dial indicators) to the center.
But placing the sprag clutch at the engine instead of the rear hub changes the model of overrunning clutch you will need and keeps a lot of stuff spinning when you're coasting that shouldn't be. Definitely not the best approach imho.

Actually, the spline is integrated into a plate, which is then riveted to the clutch drum. Build new plate with over-running clutch, punch off old plate, bolt or rivet new one on. Easy.
This would not be at the engine, though. The clutch is not on the engine in this bike. The only thing spinning is the rear tire, drive shaft, 1 fixed gear shaft and the clutch driven shaft with the clutch drum on the end of it. It really does spin rather freely, with some good gear oil in it.
