Yes, Darkseid can technically resurrect his minions, but they are a shade of their former self. He can't exactly restore souls, I think the power lies in DCU's version of God. I think Nerve Beams would be electric pulses that disrupt the nervous system. I am not sure about Force Bolts; but you might want to consider that the New Gods are fueled by the use of new technology. They should be pretty powerful in the 31st century.
To be honest, you might want to write a Fourth World set after Orion kills Darkesied. That way you can create other New Gods and not be restrained by continuity.
