Yes but for this you need to break into the control mechanism and/or the
software and neither is too easy to do ... but I do not speak from actual
experience and it may be easier then I think.! Or you can resize to fit but not
best solution is it ... but it sometimes works.

As stated earlier this _is_ a concern for high quality reproduction. Scanners
are not designed for dealing with the wide luminance range of many natural
scenes.

Crummy. Poor. On both counts. But used in B&W mode in particular the system 
works well for what it was intended, meaning DEMONTSTRATION of principles.

I think this would save you a lot of hassle. But some LOVE to TINKER and for
them such a project is fun just for the sake of doing it. BTW, some of the
highest quality digital pans photos are those precisely made with linear arrays
and rotating, scanning, cameras.
