I heard Bleach isn't as popular in Japan as in the west. I think in Japan they replace Bleach with My Hero Academia maybe

Big 3 was specifically a western thing, Naruto isn't even on par with One Piece over in Japan. There's no altering the Big 3, it's just a capsule of time in the 2000's when anime/manga was going through a big boom over here, and those were the prominent battle shonen at the time leading the charge, so to speak.
