Also, one doesn't fly a wing down, crossed controls approach in big jets.
I wouldn't be so sure about that. After explaining the side-loads issue, my MD/Boeing FCOM says:
Below approximately 200 feet AGL, gradually apply rudder so as to
align the longitudinal axis (heading) of the airplane with the runway centerline. Control lateral drift by applying aileron into the wind. (the upwind wing will be lower), while continuing to apply opposite rudder to maintain fuselage alignment with the centerline of the
runway.
This technique was introduced only in the last year or so.
Bear in mind also that as the autopilot has no rudder channel every crosswind autoland is crabbed on touchdown.
I assume the Autoland crosswind limits are way below maximum limit...
