Thats not how Marvel runs things, though. They get a director that will make the movie that Marvel wants them to make, or they'll find a new one. Sure, it's cool when a director adds their own flair to things, but outside of Guardians & Iron Man 3 there really haven't been any Marvel movies that were had anything in them that I could say was "distinctively" in a director's own personal "style".
Favreau's Iron Man movies could have been directed by anyone (& he was replaced in the 3rd one as director), Whedon's Avenger's would have been a similar flick if he didn't direct it (but still wrote the script), the first Thor was directed by Kenneth Branagh & it'd be hard to know that by watching it. Thor 2's Alan Taylor had worked on Game of Throne's, but I didn't notice much in it besides a darker tone that I would say was influenced by him (& that was probably the script), & Marvel famously canned Edgar Wright cause he didn't want to make the movie they wanted.
Sure, if Jolie gets the job & ***** everything up I'll be proven wrong, but with Marvel's track record I just don't see them letting anyone fail.
