First of all that would be WAAAY too many characters.
But let's think... Who would've been in this game? (4 reps per series max)
Kratos, Athena, Deimos? PaRappa, Chop Chop Master Onion, (Lammy), Princess Plump, Princess Muffintop (with different move-sets), Sweet Tooth, Dollface, Mr. Grimm, Calypso. Colonel Radec, Rico? (Lol, don't really know the Killzone series too well) Sly Cooper, Bentley, Murray, Carmelita. Nathan Drake, Sully, and maybe that one girl... Big Daddy, Big Sister, Heihachi, Jin, Kazuma or whatever, Toro, Kuru, Pierre, Cole MacGrath, Evil Cole, Zeke, Nix. Jak and Daxter, Keira, Samos, Veger? Ratchet & Clank, Qwark, Nefarious, Spike, Specter (also don't know this ape escape too well), Dante, Vergil, Kat, Sackboy, ??? Raiden, Snake, and that one lady? and that other guy? Lol. Nariko, Kai, also that final boss guy, Sir Daniel, Kiya, Zarok,
And just to make y'all happy, Crash, Coco, Crunch, Cortex.
