if you're going to replace the OG's, pick ONE character for each of them. they don't each need five half-assed interpretations of themselves to make up for one character.
Lantern Corps might be an exception to this, but there are still way too many earth-based Lanterns to make any sense in the overall structure of the Corps. some of them, if they still need to exist, should be moved to other sectors that don't have any species capable of using the rings - of which I'm sure there are plenty, when the total number is 3600 or whatever. then it could at least be explained as earth having "an extraordinary number" of potential ring-bearers, while not over-saturating one lone sector with them.
