It'd be almost the same plot for Log Horizon, but its not a bad theory. Kinda of a they were trying to summon something new with a portal spell, but it keeps summoning random people from the game as its shutting down and as the portal gets weaker and weaker how much gets pulled changes. Maybe Nazarick and its denizens were the last thing to get pulled as its final Hurrah so to speak.
