I had a similar thought this morning. A realigned NL East of NYM, PHL, WAS & PIT makes sense to me, assuming that at some point MLB will go to 8 divisions of 4 teams. Let ATL & MIA pick up some other pair of local teams (Tampa + some expansion team in the Carolinas?). Same thing on the AL East side - NYM, BAL, BOS and some 4th team that is geographically not too far flung (TOR, CLE, or DET being the most logical choices, probably TOR which would allow them to keep CLE & DET in the same revised division with the White Sox).
