Shinjuku Gauntlet but with previous characters
We know that by the end of the series the entire cast is more powerful than ever, but there are still characters that have died who shouldn't be too far behind strength-wise.
I was wondering how the showdown would change if you were to replace the existing combatants with characters that have been defeated before. Say Ryu, Uro, Jogo, Hanami, Mahito, anyone.
Only caveat is that you can only replace characters who are at least in the same grade/comparable in power, otherwise you could replace Ino with Yuki or just have all the disaster curses + ancient sorcerers jump Sukuna at the same time.
Would Shinjuku have been easier if instead of Hakari they had Jogo to fight Uraume or Sukuna? Even a Mahito stuck on his Shibuya self to replace another character. There should be at least a few interesting combos or matchups (say, a Curse Naoya replacing Maki, or even just normal Naoya + Todo).
