The amount of duck tape that is used in Space Mountain to support the tracks and building would make it more profitable for Di$ney to buy the factory (announcement D23).
But harsh reality aside, this ride is old, rough and a hazard. So what if we get the accompanying Dole Whip shaped building that goes better with the whoopee cushion that is Tron. What if we get a pre-show that we had in Alien Encounter (best attraction Tomorrowland ever had) and then are off to visit the alien world in the new coaster using a horizontal lift with a spaceship above us and lazers presenting the tractor beam that pulls us up in space. Then we go trough space and worm holes to end up at their planet. Arriving in the station we found out that the alien that once got into the auditorium has come to their planet and slaughtered everyone. Blood dripping from walls, corpses ripped open and a bloody set of Mickey ears that we can buy later in the giftshop. But wait this is a fakes station (yep rip off Universals' Mummy ride) and of we go to end up back on Earth.
