Honestly, I think a bigger revolution would be making "the legend of Zelda" actually center around Zelda. Not "save her because that saves hyrule", but have a very strong intricate story that all revolves around what Zelda has done in the past and what she has to do in the future to prevent other things from happening.

Playing as Zelda isn't a "bad" concept, but there would be no reason to save Link... his life doesn't control Hyrule.
