Clouds in Blender 2.8 | Dogfight scene above the clouds

Hey folks,
Im Currently working on a project of a Dogfight between Tie-Fighters and a X-Wing above the clouds. This obviously involves Clouds, but I can’t figure out how I can achieve a High Quality Cloud “carpet”. All ways I tried didn’t really work and im quite desperate at this point.

This is how I would imagine the Cloud space (best case scenario)

I hope someone can help me with that, I would be quite thankfull :^)
