As have I. Did the whole picture thing with the Captains hat and everything for a family on my last trip.

But I'm sure that you can see the difference between a little cockpit visit while sitting at the gate with the parking brake on versus giving a tour during takeoff or landing. Likewise, I think there's a difference between arranging with your boss for a tour of the tower for your kid while you are off duty versus bringing him in during your shift to man the radios during the evening push.....but admittedly, I'm in the minority here.
