I like your idea except I would put the Marlins and the D-Rays in the same division. Florida baseball, if it is to survive, needs to have a natural rivialry. So put the Marlins in the AL South. In additon I would move the Blue Jays to the NL East and add Nashville in the NL South. In the AL I would move Arizona to the AL west and Add New Orleans to the AL South. I would also move the Tigers to the AL East. Finally I would shorten the season by 20 games and add another teir to the playoffs by having two Wild Card teams NL East NY, Pitt, Phil, Toronto NL North Cubs, Stl, Cin, Mill NL West LA, SD, SF, Col NL South Hou, Atl, Wash, Nashville AL East Bos, NY, Bal, Det AL North Sox, Cle, Min, KC AL West Ariz, Sea, LAAAAA, Oak AL South New Orleans, FL, TB, TX
