Frequent flyer, I guess producing the 757 would be an issue because only the drawings are left. Aircraft these days aren't build the same way they did 30 yrs ago, margins, modularity, automation etc. dramatically changed. I guess many drawings are on film iso hard disk.. And the production lines/ supply chains evaporated.. Recreating a 1979 production line seems unrealistic. Billions of investments, many years..
Years ago I sketched a more radical 737 upgrade, $4 billion, EIS 2014

The new merged AA has a staggering 300(!) A321 on order/ in service. Plus 260 NEO options. The first new AA A321 can enter transcon service any day now.
I wonder too if Boeing will let Airbus walk away with the 200+ seat segment. They did not convince the industry the -9 will be up to par. Airlines have smart performance engineers too..
Hopefully Boeing didn't convince themselves (their management) the -9 will do just fine..
