The world of Talmud does have a few centres. The top are Ponovitch in Bnei Brak and Brisk. But Brisk has the best students because it only accepts the best. Not that the teachers are all that better than anywhere else. That leaves Ponovitch where the teachers get to that position by means of excellence, not because of family connections. And that is what tends to make the situation in which whom so ever is the top teachers at Ponovitch is considered the top of the world of Talmud. 

So what I suggest is to create a kind of Ponovitch yeshiva in every city by taking any student bachur of Ponovitch and bring him to that city.] 

There are offshoots of Ponovitch that come from people that learned there.
