Maybe, but instead of redesigning and building a new jet suitable for the larger and more efficient engines allowing their competitor's A320 to be more efficient, they appear to have kludged them onto the old (and low-sitting) 737. To do this, they had to change their location on the wing, which made the aircraft more unstable, which lead to the MCAS system to mitigate this, and problems with MCAS and sensor redundancy led to the two fatal crashes. I have a hunch many of us have seen this sort of thing and consequences before.
