Also worth remembering that airliners with 35 degrees of sweep back will have an awful lot of adverse roll secondary issues.
Boeing recommends landing in strong crosswinds with crab- basically landing sideways then correcting after main gear touchdown.
İt takes almost full roll control input to put a 737-800W down in gusty 34kt cross winds.... plenty of rudder available, the limit is roll control, keeping the wings level.
Airliner rudders are not there to side slip but to keep it straight under max take off power asymmetry. Outer engine in the case of the 747....
