Clan war army vs army

Have you ever wanted to see an army of troops fight another army? And I'm not talking about clan castles. I mean full armies. How does this work? I'll tell you. In clan wars, when you select someone to attack, you army will cross the map, taking about 30 seconds. looking like a barbarian running across the screen. Fellow clan mates can scout this army by tapping the barbarian, however the opponents can choose to attack this army. They can only do this if they have troops. When they attack, they won't deploy troops, the full two armies will just walk into a clearing in a forest and fight. Spells are deployable, and you can choose to send Heroes. If the person attacking the army wins the fight, they just prevented the attack on the village! If the army crossing the screen wins, they can choose to go to attack, or go back and re- train. You can earn elixir from doing this. Please use this idea, I think it's awesome!
