Not that I know for sure, but I would think a two speed front and rear would be impossible. I see no way to switch the two axles switch at exactly the same time. If the front is driving and one axle switches and the other doesn't there will be chunks of something scattered far and wide. That is probably why a dual axle rear is a single ratio.
