> Sure they could've redesigned the half of the plane but then it's not really a 737. That is exactly the budget and time bit - lots of time and money for Boeing spent designing a new airframe, then the "not really a 737" part means lots more time and money spent by Boeing getting it certified, and lots of time and money for their customers in getting their pilots trained for the new plane.
