I have done it once for a very good friend who knows the score and would never talk if the shit hit the fan, only a small order anyway so if it were intercepted it would just not arrive. To answer your question I would say no it is a very bad idea involving anyone else in your business on here, for a start it could end very badly for you if they did get compromised, if I were you i'd keep it simple, low key and above all else as safe as possible by involving no one else.
