I don't think that Gin would have made a very good main antagonist. Not just because of his personality, but just because of the story elements in general. Before we even knew Aizen was the bad guy, all of the signs pointed to Gin being behind everything in the Soul Society arc. The big twist of course, being that he was merely a subordinate. I don't think that reversing their roles in this arc for irony's sake would have been a very good twist.
