Hulk solo flick

I actually liked The Incredible Hulk, even if it was too generic. However, the movie didn’t make money and it was poorly reviewed. So, since 2008, the Green Goliath hasn’t had another shot at a solo movie.
But this could change starting with Phase IV. Ever since Mark Ruffalo became Bruce Banner, the hero has become a fan favorite again. Which goes to show that he is better as a supporting character than otherwise. And this could work as a solo flick if…
In Thor: Ragnarok, the Planet Hulk storyline will be adapted. So what if we get a chance to see afterwards, and after the Infinity War ends, the Jade Giant returning to Sakaar for further adventures? What if he becomes a ruler of some sort and then, at the end of his solo flick, Hulk comes back to Earth with nothing good on his mind?
Yes, a World War Hulk would be great for Phase IV, before Dormammu or some other villain arrives.
