I don't know about that but "mock" dangerous items are considered prohibited .. the (rather hilarious) display at CLE has the Wylie-Coyote dynamite-and-clock get up in their case of "items taken from travelers since 9/11" display.
I can't say I'd recommend trying to "red-team" the TSA on your own. Gitmo is unlikely, but arrest and no-fly status is pretty probable.
