Isn't that pretty much how the B-2 is controlled?

Not really. On a B-2, there is a plain flap, or spoiler, on the top and the
bottom of the wing, out towards the tip. Yaw is done by extending the top
and bottom flap, about equally. You turn to that side, in a flat turn,
though.

To roll and turn left, the spoiler on the top left goes up. Fine tuning of
the yaw and roll, and so-forth, is done with the other flaps, with the fly
by wire doing all ot the thinking.

This is all a gross over simplification, of course.
