That's awesome. I shared on another thread that I would be in favor with a Space Mountain rebuild ala Tokyo. I think if they really want to do a "New Tomorrowland" then doing something like in Tokyo would be great.
I also think that "right of passage" line is true, but now there are so many other coasters that fit that mid-level entry coaster experience that I think Space should become more intense to be another right of passage.
Plus, with no IP attached, it is the perfect ride to have its draw be primarily the thrill.
