So, I suspect that you'd end up with an aesthetically unsatisfactory wheel with really uneven grinding marks that would break prematurely.
If one trued the wheel, very true, say 1/4mm wobble/hop, then one might be able to use the wheel as a lathe of sorts. And, build a jig to do the work.
Where to take the material off? In the bead seat, or the valley between bead seats, and it severely reduces the strength of the wheel, and a E-Bike wheel at that!!!
One could grind off the hooks. It might help with mounting slightly, but risk blowouts. Or, the hooks may also contribute strength to the sides of the rims.
Aestetics won't be an issue as the grinding would be mostly hidden.
Anyway, I agree that this is a very bad idea, and one needs to further diagnose the problem/solution.
