Why not Memphis to the Eastern Conference?
I'm just going with who is closer to the coast. While both markets are lined up vertically, New Orleans is actually a lot closer to the Atlantic ocean due to how the coastline runs in a southwest/northeast direction. Therefore, the areas farther south in the southeast region of the country wind up closer to the coast.
This is merely what I would do. I have no idea how the league would go about it. Maybe they take into account how much certain ownership groups complain about their respective alignment. Memphis complained for a long time about being in the WC but that had more to do with competition from the WC being stronger than the EC. Now that things have evened out a bit, they may not care anymore.
