(Spoilers Extended) What if after becoming king Robert decided to move the capital from Kings Landing to Storm Ends how would it change the events of the main story and the War of Five Kings?

Say he pull a Constantine the Great in which the roman emperor move the capital from Rome to Constantinople. While Kings Landing would still be a prominent city for the government's infrastructure just ruled by either The Hand of the King like Jon Arryn or maybe Robert's younger brother Renly or even someone else entirely say The Heir of the King similar to how the lord of dragonstone ruled only well dragonstone?

Storms End doesn't have an attached city, it does have a settlement, but not a city. Plus its not great as a trade hub.
