This actually is what will happen.... Knowing that Mihawk hasnt had a fight since ever... and lives only from hes Hype that nobody really cares.... everyone in the story treats him like a child who believes hes accomplished something, its laughable, only zoro treets him seriously... in the entire story theres only like 3 swordsman discounting samurai who dont care about WSS title either.... So when mihawk will see that Zoro improved he will give the title away
