Inspiring idea. I've just taken up LF a while back, my two enlargers I need for 35 and MF so was considering using a spare Calumet cc401. Removing the gg for the light source and using a film holder for the neg could work,perhaps. It has a max of 22'' of travel on the bellows, I used a lamp for a crude test with my 305mm LF lens to see how much projecting at maximum I would get, very little it turned out, I had to retract the bellows almost fully to get enough coverage for even a 10x12. I'm assuming by using a smaller lens,perhaps a 150mm proper enlarging lens I would achieve more coverage? Obviously I haven't thought of a way of using the camera vertically yet, but that shouldn't be too difficult.
