Respectfully, I don't think you've given the issue enough consideration. You're saying that if they didn't search the pilots, someone would fake as a pilot to get through security? Then what would he do? Stand awkwardly with the rest of the crew thinking up a story to explain why there are two pilots (or three, or whatever) on this particular flight? I would hope that a fake pilot would be fairly easily and quickly detected by the other pilots (who do know each other personally, after all).

I assume he would change clothes in a restroom stall after getting through security but before getting to the boarding area. In fact, that might be overkill... All he needs to do is put away his jacket and hat, maybe put on a sweater -- actions innocuous enough that they could be done in the open.
