You might try a hydraulic jack on the axle, and chains behind the wheel, although I think PB, a little heat on the disk at the axle, and some judicious rim tapping would be my first choice.
I do think that replaceable teeth from the factory would be great, but that makes things pricier several ways. Unless you go through teeth quickly, I would make myself a jig and then silver solder new carbide inserts in. It is a quick job. If you have gone through your teeth quickly, a decent machine shop should be able to fabricate a new disk drilled for replaceable teeth pretty easily, or you could buy it from an online fabricator, as only the center axle hole needs to be cut with precision. The rest could be plasma or water jet cut. My recollection is that the Vermeer type grinding disks are thicker, and my guess that is to accommodate the greater centrifugal force on the disk from the larger, heavier, replacement teeth.
All the best,
Peter
