It sounds like the 60s again when there was a size vs. speed war (747 vs. Concorde). I think its too radical, Boeing is going to have a hard time selling them. Sure, airlines will always be interested in providing inputs for a design but when it does comes out will they be willing to buy them ??? It's too radical of a leap unless they want the new Boeings to be another Concorde or Convair 880/990s. It's just my view.
