Congratulations on your considerable background!
Now answer my question: what would you suggest instead, and why? And why does it work better than what the people who have investigated this issue have proposed?
Consider this a chance to show us your superior skills and knowledge. But don't evade the question.

The answer, patently, is: (a) because the FAA and the CAA and various other bodies have already performed quite extensive tests; and (b) because the flight departments of airlines are not equipped to perform those tests for themselves.
I take it you are inexperienced with how safety issues get approached and resolved in aviation?
