Boeing chose not to do a new flight deck beyond the screens, not because it was too difficult per the FAA rules.
What you are missing is that the difficulty in doing an upgrade itself was not the problem, it was the training costs the airlines would incur due to having two different cockpits (much like the 764). It would have caused problems for the
customers. Boeing does not want to willy nilly change things that will just create more problems for the customer, because Boeing knows that they will balk (as SWA did). They can't make changes in a vacuum.
