I used to make pear pies when the tree was giving forth, freeze them uncooked, and toss them into
my suitcase to take to my parents in PHX. This worked very well, despite a couple of necessary flight connections, until one day when NWA 'lost' my luggage. I also took frozen pies to the Caribbean, but always fruit. I sucked them into a ziplock and they always arrived unscathed and still cold.
So if you had a quick method of shipping and the pie were really reeeeelly frozen, it might work.
BTW, the pear pies that were lost with my luggage turned up a month later sitting in the luggage room where no one had ever looked for them. The pies were very sad-looking but the sucking on the ziplock was very effective. They hadn't even molded and the suction really held everything in place.
