Star Wars Episode VII The Force Awakens Drew Struzan Poster Analysis

There was an abundance of news yesterday from the D23 expo! From Star Wars Land being built in Disney World and Land, to the cast announcement for Rogue One, to Colin Trevarrow directing Episode IX.
That stuff is very cool and exciting but this poster from Dew Struzan is what really caught my eye!
At first I was quite surprised seeing Fin (John Boyega) holding what might be Anakin's Lightsaber, but lets look beyond that.
How did that monologue go in the first trailer ???
There has been an awakening...
Have you felt it?
The Dark side and the Light...
Now lets look at Struzan's poster, there's the three main characters on the top.... Kylo Ren on the right who represents the Dark side with the cold darkness of space as his backdrop and our boy Fin on the left clearly repping the Light side with the warm light of the Jakku sun behind him and smack dab in the center is Rey....
So is Rey not the hero of the ST? Up until this poster I was under the impression Kylo was the primary antagonist of Episode VII and Kira Rey was the primary protagonist....now I don't know. Does Kira represent both the light and dark sides in perfect balance?
And then we have everyone's favorite scoundrel rocking his trusty blaster under Fin.....alone...no sign of Chewie, No Leia, No sign of Luke or Leia....very odd. No sign of the Falcon.
I gotta say this poster seems lacking.
So based on this poster and recent revelation that Han Solo had a wife....here's my crazy ass hypothesis!

Fin is the biological son of Sana and Hann Solo, Hann assumed for whatever reason is family was killed by either the Hutts (debts to the mob...) or the Empire (war).
He meets up with Ben, Luke and Leia and a new life presents itself...
Han and Leia adopt 2 war orphans Kira and Kylo after RotJ and here's how we land at the above poster...
I doubt this will come to fruition but hey how much do we know about Lando...we know Hann knows him, we know Lando is a scoundrel, but we know little to nothing about Lando's family from the films....maybe Lando had a sister...
