Is it possible to change the name of a controller based on a configuration value?

What i am attempting to do is write an admin control panel for a script, and would like to give the end user the ability to change its url from its default ie: admin to a directory of their liking. Is this possible and if so how would i go about doing it?

Configure a hook, which retrieve data which has been saved in your database and manipulate the REQUESTED_URI to re-route match request to any controller.
