I see no reason why it would not work; but first you would have to shoot
three separate frames or more of the exact same image at different
exposures with each of these brackets being submitted to the scanner for
scanning.  Most scanners typically do not have the facility to produce
image files of different exposure values from an already created image
on film given that such secondary captures begin with already limited
and lost data about the original scene.

The post scan manipulations and use of layers for each separate exposure
in themselves would require some experimentation in developing the
appropriate scripts for establishing the different layers for the
different exposures.  The effectiveness of the Photoshop layer scripts
and manipulations would be dependent on quality and content of the
different image files imported into Photoshop from the scanner.
