For non metric people, your proposition is calling for something to be able to transport a package around 2lbs approximately 9,000 miles.

Flying below radar has its own challenges, as described here: http://aviation.stackexchange.com/questions/2952/can-you-act...

Your real issue would be finding an efficient enough engine to fly that far with a few refueling points along the way, thus making the trip longer than what you're probably envisioning. This is why I'm assuming jeffasinger has proposed a blimp or some form of a blimp to get this accomplished.

Yes, it can be done, but with several caveats.
