Wikipedia: Easily generate large custom palettes?
I am a Wikipedia hobbyist, and I would like to expand on the Floyd-Steinberg dithered palette examples on this Wikipedia page.

Wikipedia: List of monochrome and RGB palettes

Is there a way to tell GIMP to programmatically generate a 6-bit, 9-bit, or 12-bit color palette?

All the dithered examples you see were created by me a few years back, by individually picking grays/colors to construct a custom palette in GIMP, then translating the original 24-bit parrot/color bars down to the custom palette.

For example the 8-color Floyd-Steinberg dithered parrot and color bars, on the Wikimedia Commons. GIMP does an excellent job of making these, and if you squint at it or look at it from a distance, it looks full-color:

Sure, I'll manually create a 16-grays palette or an 8-color 3-bit color palette, but it starts to get intimidating to make a 64-color, or 512-color, or 4096-color palette by individually picking each color, one at a time.

Also, I do not see how to generate the non-regular palettes without a lot of manual custom color picking:
