Idea For a More Interesting Map and Therefor A More Interesting Game

In light of Riots recent decision to change some aspects of the league of legends lore, a question emerged from my brain. If the changes include the removal (or changes) of the Institute of War and the Summoners, then where would the battles take place? All around the world of Runeterra (well Valoran and surrounding islands) apparently. So I thought there should be different maps (or at least replicas of summoners rift) stylized as the different places in Runeterra. A map for Noxus, Zaun, Demacia, Ionia, Piltover and so forth, with architecture to go with the region/city-state. I think it would be a great way to add depth to the game and make it a lot more interesting to play on a daily basis.

P.S. A cool way to decide what map is played on is to take the home each of the champion picks and randomly draw a location randomly. (if 3/10 champs in game are from Demacia the there would be a 3/10 chance to play IN Demacia, that'd be Sweet)
