[Suggestion] create enough channel and delete overplus

I'm the Admin of a Server for about 100 User.

Our biggest problem is the amount of Channels we need. Sometimes we only need a few, but even then there is a big amount of empty channels.

I had the idea to install a bot (or run a script) thats allow to keep always 1 empty channel and creates a new one if there is no empty one.

now:
room 1
user1,user2 ....
room 2
room 3
...


my idea:
room 1
user1, user2
room 2 [empty, no room 3 necessary]

i googlet and looked in several forums, but i never seen a request / bot / script like this.

does anyone has an idea how to solve my problem?
