I would rename xsane to xsane.real and replace it with a shell script
wrapper which does something like:

#!/bin/sh
set -e
/usr/local/lib/xsane/xsane-startup
xsane.real "$@"
/usr/local/lib/xsane/xsane-shutdown

No gimp hackery required.

The two scripts xsane-startup and xsane-shutdown can contain whatever
commands are needed to initialise and turn off your scanner etc.
