I had a dream about a new league map/mode

So i played wicked league marathon one weekend, and Sunday night dreamed about League. It was not summoners rift. It was not the Howling abyss. I visioned a new murder bridge. One built in the twisted treeline. One where you can go above or below the bridge...

Spells cast below the bridge that come from above would strike those on the bridge (W from , or / 's ult). Spells that come up form the ground cast from atop the bridge would strike those below (like 's Q)

They could make some summoner spells that would allow you to climb up or down the bridge.

It was an awesome dream - lots of hexakills.....
