Here's my take on this.....I don't think they'd re-theme RoS to anything other than Superman. Think about it this way: Who, besides enthusiasts, call it "Ride of Steel"? Literally nobody. 20 years later and pretty much every park visitor refers to it as "The Superman". Say it was re-themed to The Flash.....great idea, but legit every non-enthusiast SFDL guest will still call it "The Superman", guaranteed.
