What is Friezas role in the Universe Survival arc?

Since it was clear that Frieza would return for 24 hours and participate at the Universe Survival arc the discussion was on: What is going to happen to the former ruler of Universe 7?

By now you could see a few hints that he is about to strive for more than just winning the tournament. Just shortly after his return to Earth he tricked Goku and tried to make a deal to join Universe 9 which failed because Beerus and Whis suddenly appeared. Around this time Frieza saw that the Gods are quite desperate to win and that he could take an advantage out of that.

As the warriors arrived at the tournament stage he met Frost and found out that he is quite similar to himself. They both agreed to work together at this tournament. We couldn´t see anything in that regard just yet, but it could be an interesting plot point in the upcoming episodes.

But is Frieza even aiming higher planning to rule over the two Zenos? To quote him: 'One day, I promise, I shall reign over you.'
Could this be the case if he plans to manipulate the Gods? But how? Triggering a disagreement between the Daishinkan and Zeno? Or even involving the angels?

Or what about this simple scenario: During the tournament Frieza learns about the Dragon Balls of the Namekians of Universe 6 and plans with Frost to go there once the tournament is over. Finally, Universe 6 is getting erased and Goku and Gohan are the last remaining warriors winning the Universe Survival tournament. They wish for all the universes restored and warriors of them being revived. Which also revives Frieza. He and Frost go to Universe 6, trying to get the Namekian Dragon Balls which causes another storyline along with the Universe 6 Saiyans to fight for the Dragon Balls on Universe 6 Namek...

Could happen. Since I think Universe 6 should be investigated further and we should see more of it. And Frieza going there even makes more sense since I cannot see him ruling over Universe 7 again. 

Or: Once all the universes are restored Frieza gets the offer to become a God of Destruction of another universe which even makes him a bigger threat. Maybe that could be one of his first steps striving for more with him being closer to the angels to manipulate them which are close to the Daishinkan... 

Anyway, the story is quite open right now and I don´t see Frieza just disappearing after this arc. There is now built-up which could go in another direction. Let´s be patient, enjoy this arc and we will see where it goes...
