How would I increase the max build limit in minecraft?
I want to take on the ambitious project of recreating the earth in Minecraft at a much larger and detailed scale than what is currently available. The bottleneck I'm reaching here though is the max height limit that Minecraft has. I want to increase the max y value that can be built from 256 to something in the range of 6,500-7,000 blocks. Then I want to modify world painter so I am able to create a map of the earth at that scale. I don't want chunk generation or anything else like that to really change, the only thing that I want to be different is the height limit. Also, I would want it to be possible to run it on a server. Any ideas on how I could do this?

In the latest snapshot 20w49a, you can increase the height limit with a Datapack:

You have to put it in the datapacks folder in your Minecraft world folder. The world generation in the datapack is a void world, but you can tweak it to make it a normal generation.
