Yes, could work. Since the images don't have any perspective distortion
this is the same situation like for scanned images are a long mural shot
from different viewpoints. This is called orthographic projection. You
would need to choose a very long focal length to simulate orthographic
projection and set control points on identical features between images.
Overlap should be more than only a few pixels for this to work.

Please note that current GUIs have extended old original panotools to
allow the direct use of multi-viewpoint images. In Hugin this is called
Mosaic Mode, in PTGui Viewpoint Correction.
