Well according to Lauren Faust, Twilight's destiny would have taken an entirely different route. She also intended to make Season 1 differently with NMM being the main antagonist of the season who breaks free (just like she did anyway), but continues to spead her darkness in the world until the finale. That's why we have the Gala Song as a season finale, not an epic battle with Nightmare Moon. At least we were able to witness a somewhat conceptual successor of that imaginary battle in S4. That was epic!
