You could build something like this
Wood Sports Lockers and Wood Lockers by All Wood Lockers and paint it to look like the lockers in the first film. Hang your jumpsuit and belt, stow your boots below and your small gear up above. Maybe add a "no ghosts" logo. When you have your pack done you can hang it on the wall next to the locker. As you add more gear you can either hang in on the sides of the locker or stow it on top. Best of luck!
