You can go with a staggered tire setup on an xi/xdrive as long as the rolling diameter between the front and rear tires are within 3 revs per mile.
As Tom mentioned it will give you more understeer. Essentially the car will want to continue tracking straight when you're going around a corner despite wanting to turn sharper. This will generally only be noticeable if you track the car.
