Python is the way to go for this

. I know how to increase the scale of the cloud shape generator, but the performance gets much slower as you increase scale and do lookdev. Just wanna make sure I am not missing something.

Cloud Shape Generator should not be getting any slower when playing with Initial size or any scaling parameters so you should be able to make as big or as small shapes as you need

however once you are turning you shape into VDB using VDB From Polygons or VDB From Particles, you need to adjust the Voxel Size accordingly to how much detail you need, so likely increase for large clouds

in other words both 5m wide cloud with Voxel size 0.05 and 50m wide cloud with Voxel Size 0.5 will be roughly 100 voxels wide
and therefore the subsequent Cloud Noise with relatively scaled size related parms like Amplitude, ..., should take roughly the same amount of time

there is also no harm in scaling your cloud volume at the very end, and dividing the density value accordingly if you want to keep the same visual density

You may need to turn on Caustics for this and increase Diffuse Limit to at least 1
In Karma CPU you can potentially also turn on. Guiding to help them resolve quicker
