Yes, hopefully something like this will do it:
pkg_preinst() {
main_active_python=$(eselect python show)
}
pkg_postinst() {
if [[ -n $main_active_python &&
$main_active_python != $(eselect python show) ]] ; then
einfo "restoring active python interpreter"
eselect python set "$main_active_python"
fi
}
