Space mountain is a classic and beloved Disneyland attraction, with good theming on the interior, that has entertained Disneyland guests for decades. However, due to a lack of an in-house popular science fi/sci-fantasy movie franchise, Space Mountain has utilized a generic outer space theme, perhaps riding the Star Wars wave to some, and being boldly independent and creative to others.
Now Disney owns Star Wars.
What if Space Mountain, and the section of the People Mover track heading down Tomorrowland's main thorough-faire, was retooled into a 'Star Wars' mountain experience in which guests would still soar through outer space with projected stars (and with perhaps a Star Wars space battle added on), in addition to some Star Wars dark ride scenes and a moderately paced tour of Tomorrowland via using a "loop" of People Mover track behind Star Tours/Arcade, and around the old People Mover loading station which would receive its own special Star Wars theme. (This would involve major construction and likely demolition of the 3-D theater).
