Of the films you've mentioned, Scooby Doo is the only one that is based off the movie version. The others are generic 'comic book' versions. Scooby Doo was also filmed at the studios, which TBH I think is the more likely the reason for the Scooby theme than a desire to promote the film. I'd also say it's waaay more likely that Superman Escape was capitalizing on the upcoming movie rather than being an early promotion for it. Same with Green Lantern and Wild Wild West.
It's also no secret Warner and Village have a good working relationship; they partner in movie production, distribution, cinema management and (obviously) theme parks. The important thing to remember though is that for the most part, WB doesn't say: "You must build a ride based off this franchise to help promote it", rather Villiage Roadshow say "We want to use this character, how much will it cost us"?
