How to multiple falloff FOG masks in VDB?

I want to scatter in space a bunch of spheres, each one being a different FOG volume with a falloff density.
I want then use them all together as single mask in a “VDB reshape” node.
I tried 3 different ways, from left to right:
1) It works but it's much inefficient: too many points.
2)It works but it's SUPER inefficient. Too many volumes are being created.
3) Another approach, it doesn't work but I can already see it would be SUPER inefficient. Again, too many volumes.
Please have a look at the project file!
I guess there's very simple way I'm completely missing :p
Thanks!

ps. I'm using the mask for a ‘VDB smooth’ node and I'm noticing that the whole Geo is getting a really small amount of blurriness outside the mask (even outside the bound of the FOG vdb used as mask, which don't cover the whole Geo, as shown in the picture).
This very little overall smoothing is not a big deal, but I'm curious to know why it's happening outside the mask.
Any idea? (-:
I attached a simple project file that shows this small issue.
