Procedurally generated planets

Just thought of this:
What if when you open a new solar system or specific game mode you can put in a seed if you want (yes I know, like MiNeCRaFT) that generates a random amount of planets, moons, asteroids and comets. However, the body's are within certain parameters i.e. their planet type, atmospheres, size, shape, surface terrain and types of biomes found on them. This would mean that when you make a new game you have no idea what the atmospheric composition, terrain, and moons of any planet are going to be like, this means the science and exploration of the solar system will be super unique and different every time.
I know this would be a nightmare to code and generally make but I think this would be a really cool addition to the game. But as this game is still heavily in development I understand this is far from first priorities even if it did make it into the game.
Thanks, and if you like this idea, pLEaSe UpVoTE :)
