If you don't think a genuine World's First coaster is worthy of an SW tag then you're going to be dead disappointed at the "World's First roller coaster to infuse Wood and Fire" or whatever laughable tag they've put on Wicker Man.
I think Rita needs to be moved to another park and that should be the sight for SW9. If you got rid of Rita, it's associated buildings, the food outlets, lockers, arcade and used the space behind them plus a bit of space behind Burger Kitchen there's a fair bit of room there for a decent launcher. Perhaps a double launch air time machine or something like that.
Alton definitely lacks launches and air time and it could solve the whole Dark Forest theme problem by demolishing the UG Land buildings and creating something that at least wouldn't look out of place next to Thirteen, even if that means the area gets a retheme that matches both coasters.
