I would think that securing the bushings/bearings with Loc-tite (sleeve retainer) would be fine for aligning them with the shaft. The issue then would be aligning the shaft to be parallel/perpendicular to your grinding wheel/cup so that it tracks correctly across your abrasive. You may have to shim/adjust your base castings to do that.
As long as the shaft is pointing in the right direction when you are done, I don't see a problem with it myself. Mill heads are accurately bored and tightly fitted with precision bearings. Does that mean the spindle is always in tram with the table?
