there are hardly any events,tournament, or any other things in clan environment that are automated. Ally treatment should have been in their clan's leader discretion on what they want to do with allies. For example, Liquor host monthly event on their board that only allow member and their allies to participate, they also hands out the password to their private board to picked ally on their ally list.

Honestly, ally system doesn't hold any significance to become a good clan and there's too little things that this "ally list" can do if this got implemented.

My stance for this matter is not supported until someone actually gives a decent idea about this.

P.S. Why would you want to ask someone not in your clan do your clan war to begin with?
