Disagree. The iconic Jedi look w/ the robes and lightsaber is a huge brand. Once you make everyone a force user, it removes that as a plot device. The whole idea of training as a Jedi and being a Jedi Knight is a huge avenue for books, games, comics, etc.
Plus -- part of what made Star Wars "work" (and what was missing fron the prequels) was characters who the audience could identify with that didn't have magical powers. Han Solo was just a badass pilot with swagger -- he didn't have magic, he had simple tricks and nonsense. Kids may have wanted to be Luke, but Han was the audience surrogate.
