Hate to say it, Warlord, but I think everything in your post is factually inaccurate.
Start with replacing Bernacke .... His term lasts until 2014, and the Prez [Romney or Obama] does not have the power to fire him. Romney's assertion that he will fire Ben is just more lies from the biggest liar in Presidential history. So, don't count on a change one way or the other.
QE3 is not slated to expire on 12-31-2012; it is going to continue indefinitely. It is Operation Twist that is slated to expire at the end of the year, but that Operation does not add liquidity to the economy; it just attempts to flatten the yield curve.
Some people believe that the Fed is in the President's pocket, but I don't. The Fed is supposed to be independent, and I believe Ben is. Regardless of the Prez, Ben will continue to do what he is doing. So, the idea of a fiscal policy with regard to the Fed draws a blank stare from me.
I think politics is important with regard to the Fed, but mostly from a perception point-of-view [like yours], and not because there will be much difference.
I suppose anything 'could be,' but there are some procedural things that can be done. With a supporting congress you can absolutely cause an unelected bureaucracy to toe the line. It's happening now with various agencies via the Obama administration. Pressure matters.
Add to it, this is an agent of the people created by the congress. Obama didn't pass obamacare by the technical definition, he only signed it into law. In much this same way, presidential leadership can invoke change within an agency very quickly.
A few google searches will reveal some of the technical details of the ideas in this area.
