From the Department of In the Future: The Major League roster isn't big enough to accommodate this idea, but the most efficient way to use a pitching staff might be to ditch the whole starting pitcher concept and instead, have a handful of pitchers, each pitching no more than three innings, pitch each game. The pitching staff would essentially be comprised entirely of relief pitchers -- and all pitchers would be groomed for a reliever's workload. The game is trending that way, but again, roster-size limitations are an obstacle to this idea. All pitchers, from the stars to especially the fringe pitchers, are less efficient with each incremental trip through the opponent's lineup. In a relief staff, pitchers wouldn't have to pace themselves to pitch six or even more innings a game, and the batters would rarely see the same pitcher twice in the same game. Or, to mitigate the need to use the shorter bench as much, DH.
