have you never tried some fake caustics using texture on an area light? Something like a caustics projector
But you also need to make sure they don't appear in shadows from the sun...
If you put opacity to 0, your area light is invisibile to the other light source (if I understood what you wrote)

No, there is always something in the pool (or it might be pool itself) that casts some shadows.. In those shadows caustics cannot appear.

If you project caustics from top down then they will appear everywhere - even in shadows... The only way could in theory be to project them at the same angle as sun, but then you cannot make sure they appear only within the pool properly.

It cannot be faked in a meaningfull and acceptable way in luxcore, but i repeat again.. I'm not looking for workaround, if I was, I'd use cycles where I get the flexibility. I need best looking caustics everyone ever seen :D

ah..right... in the shadows there is no caustics... ok... no... faking is not doable at all. You're right
