Ah, but it's fun to dream. :o)
How about this one then:
Take three of the IPIX lenses, mount them back to back with a periscope
assembly on each of them. The periscope transfers the image circles down to
a full frame camera. I did a quick test in Photoshop, and there is room for
three of these 14.9mm image circles on a full frame, with a tiny bit of
overlap.
So, instead of pointing a camera up into a mirror, you point it up into an
array of three lenses, each of which records to a 14.9mm circle on the
sensor at the same time.
That would give you enough overlap between the lenses to compensate for the
light falloff. Then, write actions in Photoshop to extract the three areas
into separate images and stitch them together. Might even work for video?
