Someone needs to get an out to grass A330 on the way to a boneyard and actually replicate what happened. Good VFR with a clear horizon over uninhabited desert or sea just the thing for a test pilot to try.
Why? Why is this important? we know what happened. The objective is to keep a commercial jet airplane inside the flight envelope it was designed for and not test it for responses way outside of the flight envelope. IMHO, it would be much wiser to take the money and apply it to this:
In the absence of any reliable speed indications, understanding of the overall physics of flight at high altitude could have considerably helped the pilots to anticipate the rapid degradation of the situation. The same applies to the overspeed phenomena that have evolved with modern aeroplanes.
Consequently, the BEA recommends that:
€ EASA define recurrent training programme requirements to make
sure, through practical exercises, that the theoretical knowledge,
particularly on flight mechanics, is well understood. [Recommendation

And, if this is done on a pass/fail basis, perhaps those that don't comprehend will be given remedial training until they do fully understand before returning to a seat in the cockpit, if they ever do.
