While I'm not sure if it would work, I don't think it's TOO far out of the realm of possibility.
I can see walking through a queue, getting in a ride vehicle, experiencing that part of the ride, and then getting out of the vehicle. This first "ride" is now over and the vehicle leaves the area to loop back to the beginning. Now you are on a specific path, I'm assuming with possibly two guides, one in front and one in back. Now the path you are on is restricted with possible live actors playing Storm Troopers or whatever in an area that is not accessible to the public (think Madame Leota in the Haunted Mansion). They put on a little play, do their bit, whatever, then you walk to another ride vehicle that looks exactly like the previous one (think "it's not safe to go via space, we'll have the ship loop around and pick us up on the other side") and then you finish the ride experience.
In essence, it sounds like it's going to just be two rides connected.
Too Long; Didn't Read
I can see it working if it was something like Queue1, Pre-show1, Ride1, Queue2/Pre-show2, Ride 2.
I can think of nothing more irritating than getting on to an attraction, going half-way through, and having to get into another queue before continuing on. I don't disagree that it is possible - I just don't think the pay off from it would be worth the annoyance. Utilizing an innovative ride vehicle system could provide several different perspectives/experiences, guiding through various scenarios without the problems of loading and unloading, and being able to control the entire experience. Anyway, this rumor is kind of a dead horse at this point. We have quite a wait before we get even the littlest tidbits of what's to come.
