I once disassembled my scanner to investigate the
possibility of removing the entire "plastic edges
of the scanner" all the way to the edge of the
scan area.(Hoping to be able to scan old books
only open to a 90 degree angle.)
It looked like a good idea because the outside
track is inside the scan area. Unfortunately
after I got the scanner apart, I discovered that
the xenon(or whatever) tube not only does not light
all the way to it's end, but it also has an
electrode at the end. It just sticks out too far
and has to extend past the edge of the scan area
in order to illuminate the whole area.
Oh well.
On a similar note:

Check out www.bookscanner.com if you havent already. They modify a scanner
in the method similar to what you describe.

For the Amiga, the DigiView with the DigiDroid and copystand
worked like this. The copystand is actually pretty nice though and
could be used for other closeup photography work.

The DigiView was limited to the resolution of the B/W camera
you chose, as well as its own limits of RS-170 video. These
days, you'd be far better-off with a digital camera on that
copy stand.

I understand that, but at the time it was pretty impressive
and I mentioned it due to the similarities of the setup with the
copystand. It would do 4,096 colors in up to 704 x 480 (Dynamic
Hi-Res at max overscan). I've got the full setup (Digi-View,
Digi-Droid, Panasonic WV-1410 CCTV camera, Digi-Paint 3, and copy
stand) plus a Sunrize color splitter. I've mostly used it with the
color splitter, vice the camera. Now days, if I want a close-up of
something, I generally put it on my flatbed scanner with a white
cloth over it. HP Scanjet's are especially good at capturing depth
of field like this, though mine is a rebadged Relisys Infinity
Scorpion with it's internal RAM expanded.
