I don't know any time that would be a good idea...
You can run different heights on dry pavement, you'll just wreck your transfer case- ditto with running on slip surface, if they're more than 10% different in ratio you'll wreck your transfer case eventually... if you drive around on pavement with exactly matched tires in 4x4, you'll also wreck your transfer case eventually...
Another way to look at it is there really isn't that much continuous surface that would allow your tires to slip enough to justify different sizes...
As far as width, I guess you would carry a skinnier spare so it would fit front or rear?
