I agree with you that it would be nice to have, but I'm just not sure how feasible that would really be. Every ride has its own parameters for operation and every state has its own rules for adherence to manufacturers' restrictions. Rides themselves can also be so temperamental as is. Even with the same ride at two different places, they are just going to respond differently to their environments. I'm not sure I could expect both FOFs to operate the same / tolerate the same conditions as each other**, much less Goliath at SFOG and Diamondback. The same would go for Ninja at SFMM and The Bat; Silver Bullet at Knott's and Banshee; and Racer 75 at KD and The Racer.
**See infamous stories of KI's FOF causing electrical issues while Drop Zone lifted through its brakes as just one example of a location-specific quirk, something every ride has in one way or another.
