Why would they not be identical? You'd change either the Fg function or adjust F=ma (more common). The weak equivalence principle holds in MOND IIUC. You can't make a statement about the strong equivalence principle until the resolution of MOND with GR is well-defined, in which case the strong equivalence principle may still hold. Anyways, to claim that failing equivalence principle is disqualifying is begging the question since support of the equivalence principle depends on the observations... And already we observe the rotation curves are "messed up". If that means EP is violated, so be it? You wouldn't argue against a symmetry violation like CP because "it makes the cute rule fail"
