Hello
yes it is possible. I reuse mainly my script to subdivide a rectangle in rectangles from there

Subdivide given area into randomly sized blocks with no gaps

I finished a script I began some days ago. The idea is quite simple, take a grid with X pixels in width, Y in height try to put random rectangle with given size if not possible try less big rectangle. It gives that. The output is rectangles between in UV space (between 0 to 1). So this could be used for surface or whatever. If output Count less than nx*ny augment tries.

I first measure your surface and the ratio length to height. So it allows to subdivide in square/pixel your surface.
Then I apply my algorithm so it gives rectangles. All the art will be to choose not too big number of pixels if you want quite big clouds.

Then rectangles are sorted by area, but you could also choice by ratio …

Rectangles are converted to more soft shapes

Then projected on the surface
