I agree with the need of a Metroid 2 remake, and super metroid doesn't need a remake, is perfect. Seriously, I can't see any way to improve on it, adding anything to that game will do little, the game has the perfect length, the perfect music and the perfect gameplay. All I can see them doing for it would be making superficial enhancements, in the graphics with some more detailed effects and some improved midi over the original, but adding anything else would probably just ruin the game.
