I guess, especially now Wonder Woman Golden Lasso Coaster exists, but its kind of at a dead end given the way the routing has been done on the map, and if you went to SFFT you'd logically need to add SW San Antonio, and likely ZDT/Schlitterbahn.
The thing with the US is that basically no matter which way you go, there is always another park within 2-3 hours that you can theoretically add on, and you have to say stop somewhere.
The tour finishes at CP, but an idea could be to add Kennywood at the end, since its not really on the way to anywhere.
