What would you want in Super Metroid 2?

I'll be upfront: I don't want Nintendo to remake Super Metroid. Unlike Metroid I and II, I think that Super (and, for that matter, Fusion) is utterly brilliant and needs no changing, and that any attempt to change it would be disrespectful changes for the worse.

That being said...

*If* it were to happen, what would you want added? What would you want changed? How could content be added while still staying faithful to the original? I'm interested to hear people's ideas for areas, expansions, etc.

Convince me this *is* a good idea, those of you who want this! Or just post interesting Metroid ideas, that's good too.
