Sorry, no practical ideas, but I know that in the early days of the 
Roundshot's, there was a 28/35, with 28mm lens....not sure whether it was 
custom-order only, or just extremely rare, but I doubt you could find 
it on the used market anyway. I believe the same applies to the 70mm 
Super Roundshot....

I am facing a related problem, although probably theoretically for a 
long time to come (due to price): I want to use a 6x12 fixed-optics 
system for interior shots....but the common widest choice, a 47mm, 
doesn't suit my vertical-angle requirements....I know Rodenstock(?) 
makes a 35mm, but I recall it doesn't cover 4x5" 100%....does anyone 
know whether it covers 6x12?

Not sure whether I have to be proud on such extreme wide angle
requirements....8-))....the sad thing is that swing-lens interior
images are a bit too distorted for my liking....from the outside of a
building they do great, but indoors the eye gets confused and
distracted, trying to make sense of curved horizontal lines on
ceiling and floor....even a fisheye is more natural there, while the
horizontal angles are close....8-))
