I suspect that the Greyjoy forces do not include a strategically significant number of fighting forces (marines). They're sailors; their value to Daenerys is in providing transportation for the Dothraki, their horses, and the Unsullied. The Ironborn are good small-unit raiders; perhaps there's a commando role for them. Otherwise, they're sailing troop ships.

The big battle of the living against the dead will be fought by the Dothraki; a cavalry 100,000 strong. If somebody can deliver dragonglass weapons, it will be spectacular. Hardhome times ten, with a different outcome. (I'm betting on Samwell learning where to find dragonglass in his library research.)

But which battle will come first; King's Landing, or the "War at the Wall"? If Daenerys travels north, to secure an alliance with the North before taking the Iron Throne, the war against the dead will come first. With that threat behind them, the Daenerys alliance with the North will be secure, and all forces can turn their attention to unifying the Kingdoms under Daenerys.
