I would like to see this as well. I have always heard growing up there was once a rivalry between the Blue Jays and Tigers but I wasn't alive yet to ever witness those 80's teams.
I think the goal of any kind of realignment. Should be focused on maintain current rivalry's, creating new ones, and obviously try to balance out club strength. Either that or they need to do away with the division structure. Balance the schedule further and just go by top record regardless of division.
