It's not inconceivable to have a scripted session feature added to XSane in
the future.
Unfortunately, we are currently in progress to bring the code base up to
modern spec and get it properly buildable.
It is indeed an interesting idea and I will bear it mind for a future

Personally, I would probably use a shell script with some other tools like
imagemagick to perform the changes in batch.
