Whats the safest way to take PI out a customs office?

Deluge will of course be best for it. But how do you go about it since you can't take/drop stuff in while cloaked? Is it good enough to just warp at 0/further, take the stuff and go? Or would something more advanced like aligning to the next destination, so that the office is in the way, which means the second you get in range you can drop cloak and take the stuff, while aligned the whole time; make any sense to do?

Forgot to mention, in pochven
