They should bring Viper back, make it less rough and more smooth, and replace Green Lantern with it. This time, the ride will have a storyline. A sentient robot (unnamed as of now) that's known for his expertise in defending his home spaceship has been infected by a virus (also sentient), and you have to save him. I don't know what Viper would have to do with anything, maybe it's the name of the ship in the story, your ship in the ride, the name of the virus, or the name of the robot himself. But it'd be fun, and hey, a Dive Loop gets replaced by another Dive Loop. ;)
Oh, and also bring back the Chiller and keep the B&R theming. Even have a reference to the Bat Credit Card in the queue.
