I had a hunch once that Law might become a shichibukai but then dropped it. If you guys remember, Law was the guy who helped Luffy escape from the Marineford war. There is no way that the marines or WG will let such traitor work under them who helped one of their biggest enemy. Plus, not that Akainu is the FA, the possibility seem 0%. Still this is just my opinion and I may be wrong .. .. who knows .. the "Righteous throne" Law was mentioning about was a vacant post of Shichibukai after all. He did stay behind in grand line while all other supernova were already entering the New World.
