Earth VS Runeterra mode?

here is an Idea that I had, it is a new game mode where you can play as most champions and as 10 of the Superpower nations on Earth. It would be in first person mode, as the Earth nations you can choose to be either an Infantry soldier or a vehicle or a tank. The victory conditions would be like in Summoners rift. And unlike the champions who can buy items the soldiers of Earth can buy supports such as an Artillery barrage, attack helicopter or Air strikes. let me know what you think
