What would Yuna's final aeon be like?

[Roogle]

If Tidus was her final Aeon, I'm guessing he'd be pretty damned similar to Braska's Final Aeon, for obvious reasons. Mind you, the bond between Tidus and Yuna was different to the one between Braska and Jecht, so who knows what that might have produced?

I am not sure what it would look like, but I think that it would amplify both characters' affinities for White Magic. I think that this aeon would be more powerful than other Final Aeons because of the bond shared between Yuna and Tidus.
