YOu know, this is asking too much, but, what may keep interest is to run an older parade and the current one on different rotating days. They keep much of the older stuff so it likely would be possible but I'm sure the setup would be very difficult if not impossible. HOwever , it's a great idea.
The biggest travesty is that Epcot lost it's parade and it's not been replaced. It was much better than the MK parade in my opinion.
