You don't need to do that. All you need to do is check ProjectPokemon.org once a distribution goes live. Someone will inevitably upload the Wonder Card. Just download the Wonder Card, use *hax to extract your save, use PKHex to inject said Wonder Card, inject your save, then receive your gift. For bonus points, set your 3DS' date to a date that's actually in the distribution range to make your new Pokémon indistinguishable from one obtained the "proper" way. So, for US Hoopa, set your 3DS to a date sometime in late November/early December.
