Well I tried a lightweight driver (or a least shaft - 47G, thin grip, etc.), and saw 5mph increase of clubhead speed on the launch monitor. So some of these ideas can work.
I wouldn't doubt for a second that there are some changes in the set up of a club that would give you increased clubhead speed. But not all of those that do will result in greater driving distance. And of those that do, not all will be neutral with regards to you ability to control the ball.
