Great idea of making the Nether dimension into something entirely different! I'm curious about the result.
I suggest copy pasting by using MCEdit
https://www.mcedit.net or something like Async World Edit. I don't have any experience with these mods but I've seen other recommend it for big World Edits.
I found this post beceause I'm searching for a collab for a survival map with the main focus on playability in vanilla survival and with some inspiration from Eldaria V3. Perhaps we could work together?
