Clan war battlefield

I dont know if this has been said or thought of so I'm not trying to copy anyone. A clan battlefield could be established between two clans maybe the top 5 or so ppl or have leader pick. One large field for the battle, about hour prep time, you could have objects to place or allready in place. Set up your troops, and go at it. There are so many different variations i cant even list them all. But I think this type of battle would be really fun. Any feed back is cool. Thx for reading
