There was a pair of Elseworlds mini-series called JLA: The Nail and JLA: Another Nail both written and penciled by Alan Davies that had Superman raised by an Amish couple because the Kents got a nail in the tire of their truck when they were supposed to find him as a baby and how the DCU gets really screwed up, (especially the JLA) without Superman. The villain in the first one was a real shock when I first read it.
