We will see. Part of the avionics design is that there is a “Brick Wall” between the two sets of sensors, air data computers, and flight control computers. If the FCC uses both for MCAS, that safety concept doesn’t exist anymore. That is certainly the reason they didn’t compare the AoA sensors in the MCAS logic. I think they could probably use pitot/static as a cross check on AoA, but it has some tricky edge cases.
