To invade Summerset Isles, the Stormcloaks need ships to transport the soldiers to the isles which will be completely destroyed by the famed Aldmeri Navy which last I checked was implied to kicked the Empire (Human) navy's butt whenever they clashed.

Stormcloaks is even better, they don't even have a navy to cover the ships transporting soldiers. So chances is very little. The best they can do is wait for the Aldmeri Dominion to come to them.
