Would it be a sacrilege?

The boys in my house have quite the imagination. It's not at all unusual to see them in dress up throughout most of the day...construction worker, fireman, army man, cowboy, football or baseball player, or anything else they come up with. I caught Charlie in his fireman hat and badge out on the patio tonight putting out a "fire" with his tree branch "firehose." So, my question is real...would it be a sacrilege to have a priest outfit in the dressup box? If we're trying out potential vocations, is it wrong to play mass, annoint, or baptize? Just wondering.
