So I don't think this will actually happen, but as new attractions are built, it becomes more and more apparent the difference in quality between something like Radiator Springs Racers and a classic attraction like the Jungle Cruise or the Haunted Mansion. The animatronics, the sound system or even how smooth the ride is very apparent, even though Pirates and Mansion are still two of the most popular rides. So I'd really love to see Disney completely overhaul every single ride at Disneyland and install the most brand new up-to-date animatronics, sound system, lighting, ride system, etc. I realize that a recording from the 1960's (like the narration from the Haunted Mansion) might sound pretty bad on a modern surround sound system, so even though I would miss it, I would even be in favor of them re-recording the music and narration using modern technology. I don't know how long it would take Disney to complete the whole park, or whether they would do it ride-by-ride or land-by-land, but I imagine it would involve several years with very significant sections of the park closed no matter how they did it. I'm sure it would be contravention, as any change that Disney makes to a ride always is, but I think that there would be a significant majority who would be in favor of modernizing the current attractions, and even the minority who is opposed to it would be won over if Disney did a good enough job. I think it would be too expensive and too time-consuming for Disney to ever actually do, but I think it sure would be awesome!
