Gordon,
Concur. Yes, you will still need algorthims, if nothing else, for all of the latencies in the system. Looking at the multitude of sensors, they do provide the actual data that is provided solely by algorithms on other aircraft. Dynamic pitot tubes to get accurate windspeed with pitch and turns or vertical winds. Sideslip indicators rather than algortithms for crosswinds.
A complex cross check against pitch from internal gyro sensors, would allow the complete state of the aircraft to be determined, and the faulty AOA data to be isolated.
From what I read, the MCAS on the 767 tanker does have the option to compare AoA sensors and the internal gyros.
