This has been gone over before--it seems like such an obvious idea, and certainly Star Tours and the SWL seem very close, so why not? But there's no real way to do this. The two areas aren't as close as they appear; a corridor from the end of Star Tours to SWL would, depending on the route, be well over 100 meters. Presumably, for this idea to be worth doing, that would all have to be themed, and let's face it, this is the same Disney that can't be bothered to pretty up the exit hallway in Mission Space. And then there's the question of how to route it without removing backstage access to everything that needs it over there (restaurants and bathrooms). Really, I think this idea would only work if they had removed Muppets and everything east of it and started SWL there (or, alternatively, gone the other proposed direction and built SWL north of Star Tours).
