Lots of good points raised in this threads -- and lots of crazy ideas. I think one point that hasn't been raised is that in some ways, the 2012 Sox were victimized by their early success. Had the Sox performed to most people's (including mine) low pre-season expectations, you may have seen players like A.J., Peavy, Thornton & Crain moved before the July 31 trade deadline in exchange for prospects and the major roster overhaul many are advocating would have been underway.
I'm glad this didn't happen. Until the last two weeks, this was a thoroughly enjoyable season. However, the Sox relative success up to mid-September may have a negative impact on 2013.
