A few ideas.
A "spin" option for those folks that want this to be more thrilling
Tentacles that go up And out. Giving you a better range of motion
A score board of sorts for shooting the Simpson targets
Some sort of engine steam or fog effect during the ride.
These are just off the top of my head.
"Options" do not work on rides. Verily we need to stop talking about options. Universal will not do an option ride because of the issues that it causes with maintenance, technical operations, and TM operation.
Let me explain why this is not like Mission Space at Disney:
Green and Orange are not the same "ride" per se. They are two different, independent ride systems; this is to say, one can run without the other and they have zero interaction.
To run an "option" that means you have to test every combination and permutation of the different ride system. All arms running Mode 1, all arms running Mode 2, arms x-y running 1 while z runs 2, etc. That's just testing. During the design phase you have to make sure that the ride system does not come in contact with anything during the max movement of all options. Maintenance: Different arms will experience wear and tear because of which ones get used more as intense than others. That's a problem in itself. Let's say someone gets hurt. To evaluate the ride's safety you have to determine not only the arm but what mode they ran. How did they maneuver the ride. A lot more factors come into play. For very little reward.
For simplicity sake, we'll say you mean option like the up/down lever. The difference with that is that if you do not touch the lever, it will automatically profile itself to keep the wear and tear as even as possible as well as for showmanship. That means they all have to spin.
This ride was not designed as a spinner, it was designed as a kid's ride. We all talk about how this park needs more kids ride and then complain when its not intense enough. This was a nice addition for one more thing that families can do together. It didn't need to be complicated or "thrilling."
Honestly, I think turning the RV into a tea cups-style RV on an already spinning attraction is really over doing it on spinning. I don't get sick easy on rides, but i'm not even sure how i'd handle that.
Its more than it needs to be. Spinning rides make almost everyone sick.
