No shell trick possible there.

The alternative would be to replace
emacsclient --socket-name="$EMACS_SERVER" --eval "(progn $@)"
with something like:
case $1 in --stdout-to-output)
shift
output=$(emacsclient --socket-name="$EMACS_SERVER" --eval "(progn $@)")
return
esac
emacsclient --socket-name="$EMACS_SERVER" --eval "(progn $@)"
