Just compare the B737-100 with the B737-MAX and you see why they needed to add electronic band-aids to keep it legal.
They should put longer landing gear on the 737 so the engines can be a bit farther back. And maybe change the nose so it's a bit quieter. Maybe put some cutting-edge 1970's avionics in it. How about a more pleasing brown color for the cockpit?
