I actually wouldn't mind that for a series finale. Maybe one of them dies (especially fluttershy) from an unexpected occurrence? Now if I saw that, I would put my hands over my mouth, and start crying. If it was fluttershy, I would go cry in a pillow until it's completely moist. But I would love it all-and-all, because it was a kickass series ender. Insane impact on your feelings.
