LW50:
Referring to AoA as a crosscheck if Airspeed becomes unreliable has been suggested (to confirm "what is my wing doing?") as a suitable improvement to the pilot's tool kit. (A lesson learned, if you wish).
Before adding AoA crosscheck to the "pilots tool kit" it needs to be added to a display somewhere a pilot can access it.
Unless I misread something UAS blanks out the one "proxy" AoA display available to the pilots.
