[ASOIAF/GoT] What if Stannis had won the Battle of Blackwater?

Lets say in this scenario Tywin's reinforcements never arrive to King's Landing. How would the war have gone differently if Stannis was victorious?

Cersei Lannister is definitely executed. Her children's fate might depend on Davos' advice. Tyrion would be spared, as he was doing his duty though he killed many of his men, maybe sent to the wall if unlucky. Zero to minimum lootings.

Also Robb is probably forced to capitulate later on and fight for Stannis.
