The only thing I have to wonder is:
Who REALLY would be the 2nd SE rep if it's not Geno?
I mean? Dragon Quest?
I legit cannot imagine a 2nd Final Fantasy character not from 7 due to the licensing issues with FF music.
You honestly wouldn't need more music for another Final Fantasy 7 character, they could just reuse one of the same tracks from what's already inside the game. I think that's kinda a flimsy idea to go off of.
But even outside of FF7, there's Terra, a general Black Mage, Lara Croft, Edrick, Agnes, and Crono.
There's a
lot of viable characters outside of Geno, especially with larger fanbases than his and even considered more recognizable, especially compared to him, to the average player.
That's honestly why I definitely don't think it's out of the realm of possibility for us to not even get him in this game.
The only thing Isabelle being a clone really changes is now clones are an option where people just assumed they were doing echos.
This gives Dixie and Shadow more support/probability.
That's literally it.
Isabelle is a part of Vergeben's leak and was there before leaks echos were a thing why'd you think she'd tear down the status quo?
I mean if you subscribe to the Mii costume theory, which I'm kind of unsure on, Tails would fit
way better than Shadow would.
Especially outside of it, considering that he's more iconic and is more fitting for something alongside Isabelle's motif. Which where she derives from the other character, but has a mostly original and unique moveset.
But yeah, I could definitely see Dixie getting in if they give her the same amount of effort.
