Yeah, use Starspawn priests, or the Stargazer hero if you're willing to risk him. Safest approach might be to use an Astral-2 starspawn priest so he can cast Return (needs astral gems) and later on, prepare with Ritual of Returning. Defender acts first, and they can't kill you if you've already left.
God recall takes 40 points of accumulated priest level-turns.
