Some other food for thought I wanted to mention is about the music Phoenix could bring along with him.
Smash Ultimate has a generous amount of Mega Man and Street Fighter tracks, but the representation is scarce. There's only 4 non-Classic Mega Man tracks and zero non-Street Fighter II tracks. Capcom has been pushing the Ace Attorney Trilogy for a while now. Outside of Apollo and Klavier showing up in promotional art sometimes, the cast of the trilogy are usually the ones there. This has gotten me a bit worried that Capcom will only allow music from the trilogy. I wouldn't want to miss out on some Guilty Love during a battle.
At the bare minimum, the ideal music representation would probably look something like this:
Every Objection theme
Every Pursuit theme
Every Allegro Cross-Examination theme (except for the Investigations duo, which would probably be the Presto themes)
That's quite a lot, though (these are including the DGS duo). Even if you cut out some of the redundant ones (like the Dual Destinies Objections, the T&T Objection, and Apollo's original Objection), that's 29 tracks. And that still isn't a very good amount of tracks since there's no character themes.
The majority of Challenger Packs have brought along around only 10 music tracks. The only exceptions are Min-Min (who brought 18 tracks, but it's owned by Nintendo so there wasn't much of a hassle adding them) and Terry (who brought 50 tracks, but SNK loves crossovers, so no problem there either). In Smash 4, Mega Man only had 10 tracks and Ryu only had 6 tracks.
What do y'all think about this?
(Oh yeah, and the Chun-Li leak is about someone on 5chan talking about planned characters in Ultimate. The poster mentioned Hero, Steve, Sephiroth, and the Geno costume being planned, along with the rejection of Sora, the replacement of Chun-Li by Ken, and the mysterious absence of a Tales protagonist.)
