Not impossible, but inconvenient, steering usually links the front wheels together and the back wheels together which allows for double ackerman-like (car-like) steering. The X configuration eliminates that possibility but allows for easier pivoting and as such is ideal for crab drive (translation and rotation in place only, 3 degrees of freedom)
