The controller is fired up from /system/codeigniter/codeigniter.php, around line 231.
You could change that code to suit your needs.
But I would say that is not much easier than just writing a _remap that deals with your functions.
You dont't need to put every function by hand. Just write something smart to deal with all of them at once.
