Someday - perhaps - somebody will replay the event in a simulator, and experiment some other course of actions. Perhaps ... it is done already?
Indeed it has been done already.
Your post sums up entirely the basic facts of the last minute of that flight accurately and without emotion, something which has been notably lacking in many comments regarding the flightpath and control, or lack of, in the final 700'.
I am sure I would have been as stunned and possibly overwhelmed as surely 99% of us would have been given the sudden and almost complete unexplained loss of power in that last minute.
I hope and suspect that analysis of the flightpath and alternative scenarios will be made public in due course.
