I wonder what the motivation would be for African Game Farmers to take part in that would be as well. If for instance, all the animals of Africa became much more common and plentiful to hunt in the states, then cost would go down for them in the states. There then wouldn't be nearly as much of an incentive for people to go over to Africa and hunt them as much.
Just like with most things, given enough money, someone will participate. But I'd think the African government and game farms especially would try to slow the roll on lots of live animal relocation to the US.
