Something I really loved about Disney as a kid were all the "progress" rides....Horizons, World of Motion, Spaceship Earth, and Carousel of Progress. The Carousel of Progress was great about 10 years ago, but now it's rather outdated. I would love a new script and some updates with new technology, but I bet it won't happen.
I don't believe COP fits in the Magic Kingdom at all. It would have fit in great at Epcot before they removed WOM and Horizons. Now the only "progress" ride left is SSE and there's already talk about renovating that as well. That just makes me sad. Ever since I was a kid I've loved seeing the way technology has changed over the years on these Disney attractions. It's a shame that all the rides with educational value are disappearing.
