This sounds like a great idea. Getting rid of the useless ally chat no one ever uses. And making it an admin clan chat awesome idea. It would sure help save time from switching apps to use palringo or wechat to discuss clan topics. I'm in full support chuck.
Support. But I don't think that ac should be gotten rid of. Just when you become owner/admin, you cc tab splits into 2 parts, cc and whatever the owner/ally chat would be called
