I think this pretty much sums it up. It is about getting folks into the pavilion and nowadays folks are much less inclined to see something that is not in some way familiar to them. Most folks do no know who Fingment is and have never heard of Dreamfinder. I don't think a character overlay is necessary, but I definitely think it can be done well if the Imagineers are allowed to let their imaginations run with it and let's be honest, it drives attendance.
This is the Imagination pavilion, I want Imagineers to use their wait for it imaginations and come up with something completely new. Yes, the ride was great back in the day, but I don't find it very imaginative to recreate something. Give me some new imagination to blow my socks off. They need to use new technologies to inspire new generations.
Whether it's brand new characters, Figment &/or Dreamfinder, or some other already existing characters I would love to see the entire pavilion scraped and reimagined from scratch to give us something truly imaginative.
