Well thanks, but you see, check out this picture:

I want to create stuff like this
Leaving untouched the layer 0 and 1 clouds at good,poor,hazy weather, and adding the Layer 2 and 3 flat clouds higher, at about 4km high.
Then at the rain/snow and thunder I want to have both layer 0,1,2,3 and also a few storm supercells created by 0,1,2,3,4,5 layers.

So about 4 additional layers of small clouds.

Even not, we can use only 0 and 1 layers, but I need to find a way to build supercells from the clouds, and also a way to place them high.
This is going to be trippy.
