Depending on the species, this could likely work, but it wouldn't be instant. Since the peat moss we use in potting mix is well decayed, you'd have to grow the moss, and then compost it until it's humus, and then it could likely be mixed with worm castings, compost, coir, etc, and used as a potting mix. I don't see why this wouldn't work.
I'm curious of the method you've found to grow the moss. I know of a way to make moss graffiti, where you take butter milk and a bit of moss, and blend it up, and then paint it on a wall or surface and the moss grows in whatever shape you paint it. Is this similar, or is your method different?
