I was thinking more along the lines of a tray pre-wet, then load it into the drum with the overlap referenced above.
Ilford does Warmtone in RC, I am just not sure how keen I am on selling those to my customers...
I think you'd have a hell of a time getting a wet fiber print into that drum because of the "sticky" and soft nature of a wet piece of paper. Think about how well wet paper sticks to plexi when you're squeegying the water off.
Let me know how it goes, I've yet to try large paper in my drum.
