^ that would be awesome. I also think this should happen:
-like HG/SS, have the version mascots exclusive to the storyline before the Elite 4, and get the other one later in the game, plus getting Rayquaza at the same time you get it in R/S.
(incase you didn't follow that, an example: you get WhateverSapphire. You are against Team Aqua and you get Kyogre the same way you get it in Sapphire, and get Rayquaza at the same time, but you now have the ability to get Groudon later in the game)
-there's an Underground (I really liked that) but with wifi, and also the whole secret base wifi thingy mentioned in an earlier post
-everything I mentioned before
