Giving Summoner's Rift a vibe

Okay so here's the idea, you're in champion select after waiting for a couple of minutes in queue. You pick your champion it's runes and masteries, everyone locks in. Your team looks something like this: " HEY GUYS LOOK WE HAVE A BILGEWATER TEAM HAHA COOL, I'VE BEEN WANTING TO SEE THE BILGEWATER MAP THEME FOR A WHILE" You go into the Rift, you begin to step outside your base, on your way to blue buff to leash your jungler. You step into a sandy terrain, you are surrounded by tropical palm trees, and sea gulls sit around the sand bars near the river. Crossing the river everything becomes hazy with a dark green smog hovering over the jungle, the trees are decayed and entoxicated, mutated animals rampagin the jungle. The enemy team, Time to battle Zaun.

So my point is Nation Based Maps have the rift warp based on selected themes for each side of the map. It would give a nice vibe of two nations battling in an arena. What do you guys say, yay or nay?

Edit The team configurations have nothing to do with the map theme, you could pick the map layout with having totally mixed teams from different nations, like adding a map select vote after champ select. I was just using those characters as examples
