This seams like a great idea to me.  If you disconected the internal light,
you would have no problem doing this.  You could even rig up an autoloader
for it.

However, if you "think analog" you'll see that you can in fact scan

enlargement to a piece of onion paper on the bed of the scanner would
work. 
Is that a day dream, or have you actually tried this >enlarger/onionskin
approach?  I know using a scanner for 2D-ish 3D objects works great,
but scanning a projected image?  When a transparency-adapted scanner
scans, doesn't it turn off the internal light and rely on the 
transmissive light?  Wouldn't you want to do the same with the
projected image?
