Not all CCD machines are limited by the CCD array. We often make multiple
passes on our Sony VIALTA and stitch the results together in software. We do
this quite a bit in 8 perf mode where the Neg is actually from a loads of
35mm stills camera 'motion freeze' rig. Passing the heavily spliced sequence
through twice to pick off Left an Right halves. Depending on the framing
requirement, we even use the mechanical rotate function of the motorised
imager to spin it 90degrees making each tile 1080 pixels by 1920 lines.
If we were so inclined (and so far we've not been) we could even image a
S35mm frame with the 16mm zoom lens fitted and could probably frame about 4
vertical x 4 horizontal tiles out of it for stitching together. The result
would therefore be 7680 pixels wide by 4320 lines high, imaged natively at
444 RGB 10-bit.
For a one off we'd probably give it a go, but for repeated use I think an
Imagica scanner sounds easier.
"A stitch in time, saves nine" does not apply in every case !

With a tube based machine you can zoom in to four quadrants (upper
left, upper right, lower left, and lower right) and grab these in
Photoshop and easily "stitch" them together for a high res file. Even
in standard def on our Y-Front we have done this and made many clients
happy. We have them pick the stills based on KeyKode or time code and
do the process in down time for a reasonable rate. One caveat though -
no windows b/c of the zoom.
I would assume on a HD or data tube machine using this method one
could generate a huge file that would be much higher in resolution than
the resolution of the negative. No matter how big the file 16mm or
35mm will never be 2.25"x2.25". Isn't super16mm close to the old 110
consumer format? A CCD machine is limited to the imaging head
resolution so this "divide and conquer" method won't work.
