UPD: Added more entries to this iceberg (the other three suggested by JuicePack and XeroSchnee20)
(since I can't reply to XeroSchnee20 and JuicePack, I decided to reply it myself)
Thanks for liking my iceberg! And yes, I'm planning to update this iceberg and can add all three entries you both suggested. I also plan to add an entry about Fanon SSB spin-offs (like Crusade DX, Finale, etc.).
You can check my iceberg I made if you want: https://videogamefanon.fandom.com/f/p/4400000000000190484
