It's ironic that many of the discussions about what makes WDW "bad" can be traced back to increased popularity--too many guests and too long of waits. Anecdotally, there are a lot more people visiting the parks than in the 90s and early '00s which some view as a golden age. Today, I'm not sure what Disney can reasonably to do make the parks less popular.
Building more attractions just brings in more people. The top tier rides will always draw crowds, with any potential benefit trickling down to old standbys like Star Tours and Soarin'.
The one thing that might help would be later park hours. But even that has limited demographic appeal. In my 2 decades of regular trips to WDW we went from "eh, our kids are too young for late nights" to "hey, late nights are pretty cool" to "I'm too old to stay out that late."
