There's also TEVES which is MOND with relativity, since MOND doesn't predict any of the relativistic effects we observe constantly.

The problem is, they still end up needing some dark matter before they work very well. I think every bright person assumes dark matter must be fake when they hear about it, but nobody has succeeded in getting rid of it. Dark matter plus the physics we know about is actually a really great fit to what astronomers see, and it has been hard to improve on.
