In your training were you taught to use rudder to induce the roll, if you had ineffective aileron authority ??....assuming high alpha/ low airspeed...

It's significant on many transport aircraft. DAL had an L1011 saved by a guy using thrust to control pitch when the left elevator jammed full up (Jack MacMahan). They were able to successfully land in LAX. UAL 232 used differential power to help with control.
Some safety studies blamed excessive use of rudder as part of the cause of American's Jamaica Bay A300 crash. Some 121 airlines had included a high angle of attack syllabus using rudder as a significant roll surface in the late 90's, and those programs went away shortly thereafter.
Then there's the Fairchild B-52 crash, which shows what slow speed, excessive bank angle and an overcontrolling pilot can do:
