Well, thinking more about this, there's a better approach.

An external script, wouldn't be able to properly generate missing regions and chunks or would need to pass ChunkGen commands to a running server. And it's risky manipulating region files while a server is running...

So it would be better to do this through a server-side mod.

It would have commands to: - select a major builds repository - fetch the list of builds from it - import a build into your world - generating all the surrounding region files (through ChunkGen ?) - smoothing borders on the surrounding region files - after dealing with cliffs, the biome and variants would have to propagate randomly on either side to avoid straight biome differences between the regions - eventually remapping the imported default blocks/items ID with the local ones.
