People have done it. I've seen a couple articles about it, but the one I was able to dig up today is from Mattias Wandel (of woodgears.ca note):

This isn't exactly what you're looking for, but you run into some of the same limitations using a scanner as a large format back: moving objects end up distorted by the movement of the scanner "head" as it scans the image plane.

Funny to see wandel here. I binged his channel but never knew he made articles. Anyway distortion is also pretty interesting artistically.

I scavenged a dozen of heads to make a giant wall scanning bar.
