My thoughts - In the books, it seemed clear that Jon Snow was the son of Lyanna Stark and Rhaegar Targaryen. The series is named A Song of Ice and Fire. The Starks are ice and the Targaryens are fire so he is the main character of the story. Ice first since he grew up a Stark. This will be the story of Jon Snow and his ascension to the throne after he saves the kingdom from the white walkers. Jon seems to be the only one who truly understands the threat from the north. The common phrases in the book such as winter is coming and that which is dead may never die support this. Daenerys will probably be his queen as half sister as is Targaryen custom.
Or actually since it is "A Song" it would be more appropriate to be a memorial of the story of the sacrifice of Jon Snow to defeat the walkers.Then have Daenerys rule since Martin has so many strong female characters.
In the books Jon Snow is still dead. It was shocking, but in the same way it was shocking when Tyrion drowns and you are led to believe he died. Then half a book later you find out he survived. Snow's death felt similar.
Something like that.
Daenerys is Jon's Aunt.
