I would love it if P5x leans into the possibilities that come with the multiple timelines. Remember the beta versions of the phantom thieves like Emo Haru not giving a shit about others? Make that one an Idol? Hifumi being originally one of the phantom thieves? Make her one here as an Idol.

They will obviously lean into the OC path a lot more, which makes sense with it gravitating around Wonder's story as he tries to figure out the memories and snippets he is receiving during his trip as leader of the phantom thieves but his premise has a strong gateway for alternate timeline manifestations as them. Don't forget how Reload basically handwaved the justification for Joker's presence in the Monad mini dungeon at the end of the Answer as:
>Don't think too hard about it
They have a goldmine available and I know I shouldn't get my hopes up, especially after Today's livestream being extremely disappointing for the game lasting long enough to reach that point but you understand my point, right?
