The real question is, does the mega have enough CPU power to do a closed loop/ PID controlled motion control with error correction?
A few month ago someone made a separate closed loop controller, sitting between RAMPS and motor driver ( IIRC, it was for DC-motor ).
But still there was no error correction, in case a stepper would skip steps. It would only take care of " position-signal equals input steps", but the timing could be all wrong.
