Pokemon R/S Remakes

[NICKtendo DS]

If they are going to remake RSE:
Mirage Island should appear more commonly (you originally have a better chance at getting 2 Shiny Pokémon)
The white rock near the Space Centre should have an actual function, like the Ilex Forest Shrine.
Now that I mention it, the Space Centre should be more than a building with NPCs.
Replace Acro Bike and Mach Bike with the Bike from DPPt. Going all the way to Mauville just to change bikes is a pain. Sky Pillar comes to mind.
Keep the Secret Bases. RSE were the only games to get them right.
Faraway Island and Birth Island events, since not everyone can get their hands on a Deoxys.
Battle Frontier similar to Emerald, speaks for itself.
Pokémon Contests to get those RSE ribbons for your post 3rd Gen Pokémon.
The ability to battle Gym Leaders again, battle Steven if Wallace is the Champion and maybe special guests like Cynthia in BW.
Extra areas, mainly for catching post Gen 3 Pokémon.
