Builder hall-Clan War

I think it would be nice if there is clan war in new map,however,the new map doesn't function like the old map,so I suggest that in new map clan war,every member choose some defense from their base and add to the war field(a big map in war)and co-leader/leader can arrange the base from what member provides.Wall will added in the base depends on how many member joining(each member will contribute lvl5 5walls in the war).
About traps-When 10member joined(2giant bomb+4bomb+3springtrap+3push trap provided)
*Note:The more member join the war,the less defense building members can choose to add in war map.
About attack: Because that map was big and added with defense(from players),I suggest that the destroyed building would not recover after a player attack,however,after an enemy attack,30%building that destroyed from last attack will be automatically recover.(the wall that destroyed from last attack will recover but the level of wall will be downgraded.[minimum lvl 3]
(If the clan war base have been destroyed 100%,it won't recover anymore and remain 100%destroyed)

-every player can only attack once
-Max level of barbarian,archer and minion in clan war is lvl8
-Max level of giant,baby dragon and bomber is lvl6
-Max level of cannon cart is lvl4
-If a player didn't active during the preparation day,the highest level of his defenses will be automatically choosen to add in war map.
-if a leader or Co-leader didn't arrange the war base 6hour before war day start,system will automatically choose the recent base they used for clan war.
^(If they didn't start a war before,system will automatically choose the basic base in clan war for them)
-how to win:The clan who destroy most will win(higher percentage/stars)
-win loot are depend the builder hall level.(To prevent low level builder hall player earn loot that too much for them)
-defense building request in clan war added,so the leader or co-leaders can pick the type of defense that they wanted from their member who joined in their war base.
-the defense building that more near with the builder hall will recover from last attack.
-If there is no building(destroyed) inside the wall,the wall would not recover anymore.
-player can deploy troops in the destroyed part (the destroyed parts must be big)

*SORRY that my English is suck but this idea came to my mind,if there anything to balance it or to improve more pls do let me know.
