They should go the Ace Attorney route for Castlevania; Make it as campy and close to the original video game as possible, that's how videogame movies SHOULD be. I would pay good money to see Simon whipping walls for pot roast and tossing axes at Death on the big screen. It would be a movie that only takes itself as seriously as it has to, and it would be right up Konami's alley for their goofy and lovable reputation.
