It all depends on the quality of the scanned image. I wrote a field guide
and made 32 color plates composed of scanned slide images, and it worked
great. The image processing is the easy part, getting a good image to work
with is the limiting factor.

Don't see why not. Of course, if you don't have a scanner already, and do
have a camera, you're likely to be better off taking slides, if not for
cost, then to avoid problems with magnification. It's a LOT worse to take a
small digital image and have to expand it than to take a macro lens and get
a close-up photo (at the same resolution as all the other images in one's
set) *before* digitizing. The only real advantage I see to direct scanning
is time saved. In your case, it doesn't sound like a big hurry.
