No, you're right, it isn't possible. You can't get an Anticipation Eevee with Hyper Voice and Wish. Because Hyper Voice and Wish are move tutor moves from generation 3, before Hidden Abilities existed. And Hyper Voice and Wish are not Egg Moves in generation 5 and 6, where are the only places you can breed Eevee's HA onto it. So, you can only make this specific Eevee with hacking, or on battle simulators.
However, the generation 3 move tutors might come back in OR/AS, like in the originals! So that way, you can teach the moves to a HA Eevee in OR/AS. So at the moment it isn't possible, but when the new games come out, it might be!
I hope I helped!
