Or better yet, do it chronologically, but across, not down. In other words. one division is 76, 81, 99, 03, another is 77, 96, 00, 04, and another is 78, 98, 01, 09, for both leagues. This is just my idea and I know you don't have to use it, but it's good because we can see better which eras are dominant in each league if those teams are separate.
