Editing save game raw json to alter planetary biome, weather, etc.?

Is this possible? Context: My 'home planet' got screwed over in the 5.0 gen updates so my spouse and I decided to do what someone suggested on that thread - RP a planetary disaster and the need to move to another habitable system.

Instead of relying solely on the RNG Gods we decided to be selective and seek out a paradise planet that ticked a bunch of boxes for us (namely nice weather, lack of sentinels, bioluminescent grass, peaceful..... you get the picture).

It has been So. Many. Hours. searching :( We're a busy family and don't have time to continue searching hundreds of systems (after sorting through thousands of stars). So I wondered if it would be possible to stop on an almost perfect planet and then <clears throat and mumbles> 'terraform' it the rest of the way by using a save game editor to change the planets settings?

I couldn't find any info directly on doing this. But Brave 'AI' seems to think it is possible by editing the raw json (since none of the save game editors have this function directly).

So I download the Goatfungus NMSSaveEditor and took a look at the raw json data. Hoo boy, it's been a while since I needed to edit a save game (many years ago to fix broken storyline progress) and there is a LOT more to that file then there used to be.

If changing planet data is possible, does anyone know where in the json I would go to do this? Searching comes up with many irrelevant matches :/ I'm still on the planet in question as well as having it saved to my wonders (it's the only one there).

TIA!
