How would you feel about a R2 and S2 instead of Ruby and Sapphire remakes?
Story is set around the same time as X and Y.
You start the game at a another town in the Hoenn region instead of Little Root Town. There are 2 to 4 more Gym Leaders.
Unlike B2/W2, you still get to fight all the 8 gym leaders from the original RSE. So they will be more than 8 gyms.
You stop Team Magma and Team Aqua remnants, kind of like Gold/Silver. Unlike RSE, Groudon and Kyogre never gets resurrected(That would just be copying the original game, but you still get to catch them in their original location from RSE.)
