That IS illegal. And stupid. You could go to prison for that. What will the airlines, your employer, or anyone else for that matter say. It is indefensible because it was premeditated. The more I think about it. You should turn them in. If some Tom Dick or Harry was weaseling his way into a crew line you would point them out right? Just because these guys are your friends does not mean you should be okay with that action. I imagine that knowing about something like that an not speaking up could justify your employer to yank your SIDA badge.
