I went ahead with the Quiksteel solution (technically it was a JBWeld steel stick). It works! At least for now... I took it out for a spin last night and rode it in to work today without problem. I hadn't realised how noisy the thing had gotten! Silent as a ninja now.
To true it, I removed the stator, applied the epoxy, set it in the bearing covered by clingwrap to prevent it from bonding to the bearing... This yielded a built-up axle with 7.8-7.9 mm diameter. I put it in the case without the stator with both rotor ends in their bearings and the case screwed shut to keep it true while the JBWeld cured. When I rebuilt motor I applied Locktite 609 to keep it in the bearing. It seems to work fine -- the only issue is that the freewheel seems a bit less free than it was... but this can't be the rotor because both the shaft and nylon gear clutch will be disengaged for this action. The bike performs better than it did when the problem was diagnosed. If a problem emerges with the bearing later on, then I'll cross that bridge then.
I'm amazed by how quiet it is now!
Thanks, everyone!
