A square setup is fine, since the front/rear tires will be the exact same size. This won't affect your xDrive, but it could affect the accuracy of your speedometer if you go larger or smaller in diameter than stock.
Staggered setups are trickier since you're trying to get a matched diameter with two different tire widths. Since the sidewall number is not a fixed size, but a percentage of the tire width, there is really only one (maybe two) combos per wheel size that will match.
