If they are going to "re-purpose" any of the rides, it should be Aerosmith RNC. They aren't even a touring band anymore, and the band members do not get a long at all. Not to mention they are all getting older, and it's likely one of them will pass away sooner than later.
Re-purposing the ride BEFORE that happens, is a solid plan, as it will get "uncomfortable" once a band member has passed away.
It's also probably the "easiest" ride to re-purpose. they could keep the track exactly the same, and just change the props and onboard audio.
They even keep the "rock n Roll" theme, and just change it to a younger band. Like Maroon 5 or some other terribly popular rock band. They would just need to re-film the opening video.
