I'm not sure if you can do this, but maybe you should make it so that both DROP commodities sell for say, 6k per unit at Yaren or in Rho? You'd probably want the opinion of someone from the Core, but I'd think they'd want these things stopped the most.
Either way, there's precisely zero profit involved for anyone to actually pirate anyone doing this route. The other person is only losing in actual cash 100 credits per unit and if you blow them up and bring a transport to take the cargo it cant even be sold.
