Hi background-permit,
Please look here, even though I think I should be more straightforward. The Dilate-Erode from Volume is unavailable in Fog, so I used the Thicken Object. The more I place into it, the more it feels like a hack, making me think about starting over. But perhaps that works for you. Let me know
I have placed a Copy of the original and set it to pale blue and X-Ray for comparison.
My best wishes for your project
