Anyone else think it's possible/likely that each island has something equivalent to Tapu Koku and Hala, and that Hala and his ilk could end up being the Elite 4? I'd be pretty okay with it if that was the case.
There could be a Hala for each island, and we know there's a guardian for each island. I don't think they'll be the Elite Four though. They may end up introducing the E4 one by one for each island, though. That would be interesting.
It's already confirmed by Hala that each island has its own Guardian like Tapu Koko. I'm sure that each island also has a Kahuna, like Hala, and that the Elite 4 is comprised of the 4 Kahuna, with their specialty types probably being the non-fairy type of their island's guardian Pokemon.
It would be amazing.

The champion will be Fairy type

And that would make the Champion the Kahuna Nui, the one who has mastered all the disciplines.
