clan war troops

I have an idea:

You can go to your clanwar base, and make an army there, that you use in clanwars.
Then you dont need to retrain an army 2 times for clanwars.

*You got 1 army for clanwars with the equal armycamp spaces as your reguar base.

*You can attack a guy for loot/trophies, and come home and attack in clanwars without rebuilding your army.

*Your clanwar-army cant be used in normal raiding, and your normal army cant be used in clanwars.

*You can visit your clanwar base, enter your barracks (and dark barracks), or spell factory and build spells and troops.

*You can build as many troops as you want, but the troops that are trained/left after the 2 attack will be saved for the next clanwars.

And the clanwar troops:

*You can build another building called the "war barracks" or "clanwar barracks".

*It must be built in your normal base, that can ONLY be used in your clanwars-army.

*It contains troops which must be unlocked with gems, or resources.

*It can hold up to (example) 150 spaces. (that means it can train troops for 150 spaces at the same time.)

If you have any ideas of troops that should be added, leave a comment!! I will add ideas for troops aswell.

I hope you liked the Idea!!
