You could always upgrade to lockout hubs like the Spyntechs and use the stock spare.
With the ability to disconnect the axles, a smaller size tire on 1 side won't damage anything.
A differential will handle the difference in tire size, unless there is a locker.
Running different size tires on the front axle is a steering nightmare, and adds a bit of workload.
If your carry an undersized spare and the front gets a flat the recommended method is to put the spare on the rear and move the rear to the flat location.
