A new way to make clan wars work

So my idea here is to give every clan their own "ClanBase" Which is basically a normal base that everyone in the clan can upgrade. All upgrades take the normal amount of time, but there are 4 builders already unlocked with three more builders available to the clan if the members pay enough gems. Players can kind of build towards an upgrade by putting a little bit of their gold or elixir in to the tower they want to upgrade. For example, if your clan wants to upgrade a wizard tower, the leader can ask everyone to donate 75 000 gold into the wizard tower. There could be resource storages and the money in them could only be used for the ClanBase and nobody in the clan could take money out of the ClanBase.

Feel free to expand on this idea or make suggestions in the comments below. Thanks!
