The 737 MAX would have certainly be a very safe aircraft if Boeing have taken that FBW system design from the start (as for the 777 and 787). But to make that choice Boeing needed to cancel the MAX==NG requirement and accept the additional cost of a new type rating. I suppose you could make the DC-...
