worldgen How would I create a new world on a dedicated server using existing world config?

I have a Dedicated server and I want to be able to set the world generation settings before any chunks are generated. Since there is also a mod involved I was hoping I could run a command and reset player data and chunks (While swapping seed). Ideally I would like to take the world config and put it into a new world. I want to adjust the amount of land cover without creating any sort of generated bubble around spawn and removing player data.

Also curious how this would be done. I'd like to explore a bit and make sure the world generated in an intended way before inviting anyone on. So a reset/regen with the same parameters (and seed) would be ideal. It's the opposite of the ask, but I assume related ideas. But failing that, regenerating a new world is also an option, if I was more or less happy with the generation the first time. Hopefully either one is possible.

@mudkip989 I don't know if this helps, but a previous question relates at least to generating a new file - and the serverconfig.json can contain World Configuration data, like in what is suggested you do for RiverGen:

"WorldConfiguration": {
    "landcover": "0.5",
    "oceanscale": "3"
}

You might be able to grab all the parameters from your current file and paste it there. Then run the server, once the new save and serverconfig.json is created. I'd wait for someone to confirm that, but hopefully that gets you a bit closer to an answer, or if you want to experiment in the meantime. Just back everything up first!

This is how I ended up doing it. Seems to work, but I really couldn't tell the differences much. Also time scale might not be best to touch. I made that mistake, and trying to fix it sped us past a year.
