Wrong approach
Personally I would have invited the director to join the trip as a bribe to bend the rules and allow the PFY to come along... the bastardry being that I would engineer a situation on day one involving a sedative, the director, three tubs of lard, a goat, a Filipino ladyboy and a smoked salmon... thus providing ample ammunition for future "negotiations"!
That said, the brown paper bag is one of my favourite tricks - although I prefer the air-bags that tend to be used to protect stuff in transit these days as with the paper bag you have to avoid rustling the paper!
