Tamandama attempts

You'd have to get people to comment that have experience using rockwool which I don't that much but like with any material, the more you use of it the more water it will retain.
I've never heard of it being done so if we get to see the result, I'm all for it. If it works like moss does then why not

If you want my opinion what might work well, I'd try using an old sock, fill it with matala, tie off the end and cover in moss.

As far as I can tell, rockwool has similar water retention and aeration properties to LFS (maybe even better aeration), and is used regularly in hydroponics, but I have never used it. I like the sock idea for making a ball easily, but I would be concerned about the sock material rotting. Some sort of weather-resistant fabric like fishnet, though...
