I like the way you think.
Edited to add: Since they write on your Boarding Pass at the ID checkpoint, that would show you already went through and might tip them off.
But if you printed out, oh heck, half a dozen identical boarding passes at home before going to the airport... and went to a big airport with multiple security checkpoints... {wicked evil grin}
