Maybe they can turn Green Lanterns into the buddy book?
Green Lantern Corps can be with the popular alien members (Arisia, Kilowag, etc) while the earth members rotate. One arc has Arisia, Kilowag, Bdg and John, then another story can replace John with Kyle and so forth.
Green Lanterns can probably be the book where you can do the buddy system. One arc has John and Hal then another has Guy and Kyle and etc.
Don't know if this will work but I'm just throwing out ideas.
