In terms of the title, no. As it is, Pokemon is basically limitless once you factor in Battle Facilities. Even without those the games still have plenty to do, battling and not battling. What needs to be kept in mind is the limits of the people making the game, sometimes you simply can't add this or that for some reason or another. What we have is good enough.
This idea gets brought up all the time(All regions in one game), frankly, the more regions that get made the less likely it's going to happen, eventually it'll just be too big, the best we'll probably ever get is two regions in one.
