Feel free to petition him if you want, but the last word I heard about him and playing card design was that he was through. It's been almost exactly a year since he sold this forum and AetherCards as a company is "parked," sort of - inactive but not entirely defunct, though he has no plans to revive it. He also stopped collecting modern decks - just vintage for him, now - and he sold off a fair amount of his collection when he moved out of Las Vegas. It's been months since I've heard from him, despite the fact that he does come to my neighborhood occasionally on trips as he still has family here.
What's stopping YOU from making the deck if you want it so much? Alex only showed a back as a sneak preview - no faces, no tuck box.
