In development mod known as "Erebus" Creates a new world filled with bugs and insects, new items, blocks, and music. Seems like a nice interesting and slightly terrifying mod. Maybe add it to some packs? The Erebus Wiki
Modpack developers would be the best people to suggest this to, because when we add additional mods to packs this forces everyone who wants to play to use our launcher. I would go to the creators to suggest this becuse it looks like an intriguing mod
Problem with that is it's not a Floating Islands dimension, so if it's easy to access, it'll also break progression.
