I believe theoretically, with sufficient asymmetric thrust, crab angle can be actually zeroed out as the sideslip equals the crosswind component. (Although taken to this extreme, other issues may creep up as previously mention such as asymmetric spoolup for GA, etc...)
If there is more than enough rudder authority, why do you feel differential thrust is required?
Theory is one thing, but Boeing, Airbus and other jet manufacturers don't subscribe to your theory. This should be considered a clue.
