Clan War Improvements

How about adding the capability to attack a specific clan for example maybe you and an enemy in your class both play COC and just want to attack eachother and see who wins. I think it would add a lot more fun to Clan Wars. Now of course you would only be able to attack other specific clans that are equal to yours. Yes there is the problem with making a deal with another clan and saying that it would be a farming battle where both side get money from winning battles but this could be solved by only being able to choose once a week or something like that. Good idea?
