Actually, different show outcomes wouldn't be THAT hard to program. Though I'm sure it would require a lot of computer upgrades. While each pod tilts and rolls individually (though sychronized), they're all attached to the same centrifuge. So across the various programs, the gravitational forces of the spinning are the same.
They would just have to figure out different sequences that all are able to use the same rotational programming.
It's kind of like the random programs at Tower of Terror. While there are four different drop sequences the computer can choose from, they're all approximately the same length. So, even though each car is doing something different each time it enters the shaft, they're all spending the same length of time *IN* the shaft. That way the ride time stays consistent, and cars aren't being held up waiting for the one in front of it to clear the shaft.
