r/SkyBlock

I have a realm with 9 of my friends so 10 of us in total. We want to do sort of like an Smp but everything is sky block. Our plan is to have everything be void including the nether except for the end. I have been searching for a pack with multiple islands that are spaced apart by around 2000 blocks. Where you can easily access the nether so you get 10 obsidian. But it’s also a challenge and I can’t find a single one which it’s just like the generic skyblock experience but many of these generic sky block islands so no single island is different and they all have the desert one aswell so basically like the map used in the video “I survived 200 days in Minecraft sky block“ by is who but many of these islands so we can all be separted. I was wondering if there are any free packs that do this or If I will have to make my own map. if so then how can I make one?
