I doubt that. They would never release a game with all the regions in it. Besides, Red/Blue/Yellow/Green/Gold/Silver on the Virtual Console would probably be easier/cheaper, and guarantee money. Besides, they've already remade it once, it wouldn't make sense to remake it twice.
And they should celebrate it(In my opinion bigger and more extravagent then LoZ's). As such, they should release Pokemon VC releases on the 3DS, with both Mainstream and spin off games, Pokemon Greay/Ruby/Saphire for the 3DS, limited edition 3DS like with all other handheld Nintendos, and etc.
