Flash and Gotham

Due to the comics already using the Riddler as a Flash enemy, i think they should make an episode where the Riddler, (who has already taken that persona) goes to Central City to fill the city with traps and riddles for the Flash to solve. Not only would it make an interesting episode that shows this supervillain on a show you wouldn't expect him on, but it would also hint to where he is heading to if you were watching Gotham. (which i do)
