You'd be asking people to risk a federal felony, and confiscation/possible euthanization of their pets, plus possible bad press about the "law-breaking type of people who own snakes" and the stress to the animals, all for the possibility that maybe we'd get good press out of it. Since the media is in HSUS/PETAs back pockets, I doubt it'd be shown as anything but a horror show put on by all the irresponsible freaks who own snakes and wanted to turn them loose on the innocent citizens of the US.
