I already mentioned this several times, even when I was posting my suggestions. I wrote, repeatedly, that none of these properties have taken the world by storm the way HP has. They would all require reboots, reimaginings, comic adaptations, childrens' illustrated adaptations, toy lines, etc, etc, etc, before the movies even came out to even be a contender. They could become the "New Batman Begins" or the "New LOTR", meaning movies that rekindle interest in a dead or luke warm franchise. But they don't have what is needed to become the "Next HP". Not right now at least.
