Marvin-
First thing, don't scan into JPEG.  You'll be working in PSD or TIFF to do
your color correction, adjustments, cropping, sharpening, etc., only then
save as a jpeg.

What kind of scanner are you using?  A scan on a flatbed for that size
output shouldn't take much time.  Probably less than the time it would take
to set up the artwork on a copy stand, and fiddle with lighting, focus,
exposure, etc. (as others have suggested with a digital camera - but your
question was how to simulate an SLR using a scanner, is that correct?)

Hmmm, if I understand your question, not really, other than the suggested
digital camera approach.  But then, without a filmscanner (or a hybrid
flatbed with adapter like the UMAX P-look III that I have) how are you going
to capture the negs and trannies?

I have art directed a similar project.  A 800 x 600 pixel image in a
PowerPoint presentation is very forgiving at the viewing distances your
audience will see them from.  The images will look much better on your
computer screen than they ever will on the big screen (but is fun to see
them so big!)  If you look at a video projection screen up close, each pixel
is something like 1/4 inch wide (think about 800 pixels spread out over a 12
or 15 foot wide screen and you get the idea...)
