Dunno, never having experienced either, but if I was to venture a guess, yeah, it's possible, although at a diminished rate due to small discrepancies in phase angle. Properly balanced, it's possible that each of them could perform equally to properly generated 3 phase. Bruce would be the best person to address this issue, at least from the electrical standpoint. I think that each grinder would have its own characteristics. No reason to not-----they already do have. Some are just created better than others.
