I once fitted the Commando primary works (inner & outer covers, tri-plex chain, clutch, stator mount and rotor) to my Atlas. I was stumped on how to mount the left foot rest, so I used the Atlas inner and outer covers and ran the rest of the Commando primary drive for 15K miles.
If the Commando primary works can be made to fit an Atlas, should be no problem with the hybrids.
As I see it, the main problem fitting a Commando primary cover to the hybrids, is the "in the cover" stator mount, which is easily circumvented with the Atlas stator mount.
