Didn't Vandal Savage have issues with time machines in JLU? He said in Hereafter that he couldn't go back to any point in time where he already was; even in the one where he went back to WWII, all he could do was send himself a laptop full of blueprunts and hope for the best. So if that holds true for everybody, all they'd be able to send back would be like a little hologram or something. This wouldn't require a time jump, but the league would still be able to prep a doomsday capsule/plan.
