You use a Viel, right Mr. Sharpco? Don't try edge-leading with a Scotch-Brite belt! Edge-leading into Scotch-Brite would even worse than edge-leading into leather and make for a bad day instantly.
However, I discovered how well Scotch-Brite worked by dragging the edge over a Scotch-Brite belt edge-trailing by hand the same way as using a stone. I was surprised at how well it worked. I don't know if it would work any better than your Atoma, but it's another option to play with.
Scotch-Brite is a more forgiving surface than a stone so it will be different. If you try it I would be interested in hearing how it worked in comparison to your stone.
