Our most recent example, the 45th anniversary; seemed to use Ghost for its anniversary rider. Fourze was a break in the mold and even then OOO was an anniversary rider too. Either way, I think they'd find it more important to land on the exact date of April 1st; though the rider after will undoubtedly have anniversary stuff in at least its crossover movie.
