Sure, you can have a mini-student, like a goblin or gnome. One thing that is NOT so workable is a tower of infinite space. The space limits are one of the reasons they can't just keep their students who don't want to leave around forever. This is meant to be a small island with a tall tower, with limits to their resources. Although food and water can be provided by magic, some things are still limited.
