Well the jack and the donut spare fit pretty much flush with the floor of the hatch area (actually the cardboard/carpet floor sits on the spare), so putting a full sized spare would mean you'd probably need to make a custom floor, or leave the floor out. That is, if it would fit in the hole. Also you'd probably have to find another way to secure it, since that threaded rod would be too short to run through a full sized wheel.
