KINGDOM HEARTS - Revised Theoretical 13 lights vs. 7 darknesses

I revised my theoretical take on what the next saga would be like.
Like before, the crystals serve as stand-ins for the Master of Masters, Luxu, and the Foretellers. I changed the combatants of 4 out of 7 clashes.
Sora and Kairi vs. Master of Masters
Mickey, Donald, and Goofy vs. Luxu
Ventus and Lea vs. Ava
Riku and Naminé vs. Ira
Roxas and Xion vs. Gula
Aqua vs. Invi
Terra vs. Aced

I'd consider having Lea face Gula, since both shared the role of rooting out traitors. Xion should back Lea up to juxtapose Gula's friendship with Ava.
I'd also suggest it be both Aqua vs Ira, and Riku vs Aced. Ira and Aced are the strongest of the Foretellers (as evidenced by Back Cover where Aced can hold his own against the other Fortellers (minus Ira) fighting together against him, and he's shown to be relatively matched with Ira in the mobile game, so it makes sense for it to take the Masters of the current era to beat them. I could also see Terra joining up with either.
Ventus vs Ava for obvious reasons. I'd throw in Sora and Kairi as well since Ava seems most informed outside of Luxu.
Roxas is also one of the better fighters, so I'd put him against Luxu since he's an unknown factor, and among the group Roxas has the most history what with him being Xigbar.
This would leave Mickey with Invi as leftovers, though I suppose it should at least match the Magic Specialist vs Magic Specialist it looks like you're going for.
Finally, for MoM I'd say the player gets to pick who they use against him, since facing him should occur only after the conflicts with the others have been wrapped up.
All this said though, what I really want is for them to swap out the roster a bit. I'd definitely prefer if they retired some of these characters to introduce new ones with their own conflicts, or at least relegate them to the background like they do with FF characters. If anything I'd prefer if they'd have done things Drakenguard/Nier style, with each of the major plots and characters being mostly unrelated to the ones prior.
