I hear what you're saying and I think that the spirit of it is fantastic. An agreeable route which provides incentive for Zoners to move from one freeport to the next would be a delight.
However I just have a hard time conceptually with the idea of doing it with people. Freeports have, according to their bit of infocard anyways, such subdued populations.
Technically you could evacuate the entire population of a freeport in a pair of Dromedaries... Let's not combat the logic of that right now though lest we go mad.
I guess if I just ignored the oddity of a base with a population of 250 spewing out thousands of passengers every few minutes I would be able to get over it, smile and say "right on yeah!"
