Might very well work better
That BA based pilot suggestion might very well work better (i.e., less bad), particularly if the FHA, FMEA, and SSA was carefully done, and the conclusions supported that change... good comments by both RAT 5 and Goldenrivett!
But I also concur... "Don't hold your breath!". I've been dealing with Busses and waiting for that change of heart, and philosophy, since at least the first A300B2K in the US back in the 70s, ...and then later waiting, since at least those 1982 conceptual discussions, for a better thrust solution, and sidestick interconnection solution, and soft limit solution, ...since well before the first AutoBus even flew !
