I think the NG line is still operating small scale, (military P8) and I’m sure as far as timelines go, re-expanding the line would take much less time than negotiating the purchase of another airline which takes a couple of years. I think airlines would be more inclined to buy reduced price NG’s than spend billions on another airline just to solve a relatively short term problem. UAL seems to be content buying all kinds of used narrow body aircraft to feed their growth. No hint at a buyout/merger to fill their void. I’m not saying future mergers/acquisitions won’t happen but I don’t believe the Max re-certification will drive it.
