Kevin, Chris Saenz and Max Gasman and some others did that with the Plank Gasifier. Hot gas came up through the hopper in a pipe/tube and heated up the fuel from the center to drive moisture out and the monorator removed the moisture.
Ben Peterson’s Builders Bible design has a mix between a monorator and a hot hopper. Exiting gas goes through a mantle in the hopper right before the nozzles, below the monorator.
I’ve been wanting to build a triple walled gasifier for a hot minute. But also having at least some monorator so I can use raw wood with less fuss. Downside to a totally hot hopper is apparently they can steam crash, moisture cooling the active zone too much. I’m willing to sacrifice some fuel capacity if it means I can run really raw wood.
