Map settings could use more customization

So i want to play on a very large galaxy like immense or obscene but not be in a micromanagment hell.

What i envisioned is tight clusters of extremely rare stars(low number of them) which have 2+ habitable(or extreme) planets orbiting them. Envision clusters like islands in the galactic sea (or if you want, small galaxies close to one another).

However, on 'rare' settings there are still too many stars to my liking, and if i wanted to have 2+planets per a star that would be too much planets for my liking.

Map i wanted to play is to conquer your small island (or a bigger shared one) then create military or cultural beachheads to other civs's islands, with skirmishes in the deep space for resources and occasional 'deep space' star system, however i dont think it is possible to create such a map right now.

I would suggest- add the option to customise the number of stars and a 'congregation coefficient', along with how many planets on average per star(with a % habitable and extreme), and the number of star clusters. And/or add star planet number equality slider. On high all stars have the same number of planets, and on low values there would be alot of empty stars but few interesting ones with 4-5 habitable planets.  This isnt realistic, but i think the managment of those maps would be much managable, thus making the game more fun.
