I'm pretty sure that Hell's Core would not have survived the destruction of Plutogrim by the Celestial Spirit King.

And with what they said about spreading the ressources between Tempesta's revival and changing Minerva, I doubt they would have been able to revive Ezel and/or Franmalth fast enough for the procedue to finish before the CSK went wild.
