the 35mm Roundshot is a great little camera, very sharp and easy to use. I don't have one but have seen the results. I have a couple of 120 cameras and I think they're really great machines, the only thing against them is their physical size. It's never worried me, if you're used to large format it's no problem.
I used to print the negs on a stretched enlarger I made that would handle a 14 inch neg. These days I scan and print. You could do the same with a 5 inch camera.
I posted some photos here of the enlarger a few years back, it was under something to do with darkrooms. I'm not sure how you'd find it now but it should still be there.
The enlarger was a 4x5 De Vere with dicro head. The light source was at one end so it was a simple matter of fabricating a new centre section and bolting the light source back in. Had to make new bellows as well. It would take a 4x14 neg but most of the time I was printing 70mm x 12 inches, both B&W and colour. Used it for 6-7 years with no problems. I had 2 8x10 De Veres that I was going to convert to a single 8x20 using both light sources. Never got started on that one as I switched everything over to scanning and printing.
The pano enlarger I gave away.
