Clan war castle!!!

So I thought of this today...

In clan wars, You have all of your own bases..I think it would be cool to have a collective war base between the top 5 players. That you pool together and have a war base between them, then during the last hour of the war it unlocks and randomly each war it selects 2-4 attackers that can attack it and earn additional stars between 3-5 could be used as the tir breaker or the war winner...to earn additional.bonus loot for your entire clan to share!

Your thoughts???
