Just think about it:
1. More exhibits on all the other fighters' clothing and objects: Pyra and Mythra's Aegis, Robin's coat/levin sword/book, King Dedede's throne (from his On-Screen Appearance), Gordo, and Jet Hammer
2. Even exhibits on final smashes like Link's Ancient Bow and Arrow, Masked Dedede's Mask and Hammer, Simon/Richter's coffin, King K. Rool's Blast-o-Matic, etc.
3. Statues of all the Items, Assist Trophies, Pokeball, and Bosses
4. And even replication of Stages like Dracula's Castle, Woolly World, Great Plateau Tower, Frigate Orpheon
