Would Obama hire conservatives?

It's something I've pondered for a while and generally I come to the answer of yes, he would.  Not a lot of them, but a few.  Doing so actually goes along with his message of audaciously hoping for change.  What's more different than a White House built with a diversity of views, particularly ones the administration doesn't believe in?

The other side of the question is, would conservatives serve in an Obama White House?  My sense is very few good ones would be willing to stand up and go into the lion's den to defend free markets and individual responsibility against so many others who would be hostile or semi-hostile to those viewpoints.  

The question would become where the conservatives could make the most significant marginal value.  Could ten or twenty strong conservatives in the administration be able to stop or temper the absolute worst ideas - universal health care, increased regulation of the economy, raising capital gains, etc. - more effectively than the plethora of center-right think tanks and companies they'd be leaving?  I don't know if the answer is yes, but it's something to not reject outright.
