Are you talking structurely or from a design standpoint? Either can be done. Many stores sell locker accessories that can help you add flair and add shleves, hooks, mirrors, etc. That can customize a personal locker. If you are talking structurely you will need to find a manufacturer and discuss what you want with them.
I'm sure they could.
