This probably won't happen
Depending on how the "Multiverse Trilogy" (WandaVision, Spider-Man: Homecoming 3, Doctor Strange in the Multiverse of Madness) goes, and how they connect Deadpool to the MCU, I might have to do a Marvel equivalent.
That's only if it gets out of hand, like the Arrowverse did.
Of course, if the Sonyverse became canon, Venom has an after credits scene referring to Into the Spider-Verse. I feel that wouldn't be counted, though, because every Marvel universe is connected in the same multiverse. Assuming it were, though, Earth-67 Spider-Man crossed over with other Spider-Men in Spider-Verse (comic book). I would have to ignore that. Japanese Spider-Man is going to appear in Spider-Man: Into the Spider-Verse 2.
That would mean (including rumors):
Marvel Cinematic Universe (+SPUoMC)
Raimiverse
Webbverse
Spider-Verse
Spider-Man '67
Supaidāman
Also of note, Earth-67 Spider-Man is actually an alternate version of Earth-6799 Spider-Man, who is actually the one from the tv series.
Of course, this is all just a potential future, depending on the validity of those rumours and whether the Sony Pictures Universe of Marvel Characters ends up even being in the Marvel Cinematic Universe.
