I think it would be kinda cool for Smash to embrace a little more... Fortnite-isms... in the next game. More specifically, when it comes to items. Most of the items in Smash are well, just that, common equippable weapons from the source material, with some exceptions like the Star Rod or Lip's Stick - when it would be way more fun to have individual characters' weapons in the item pool. Let Squirtle use the Chaos Emeralds or Ridley wield the Murasame or Kazooie perch on Pit's back.
