Garland,
The simple answer is yes, you CAN get a better result with a different shaft than with a more lofted head. It may cost time and money, but it is very, very possible. In fact, it is done every day.
I haven't read the particular piece by Wishon that you keep referencing, but it is inarguable that a 4 wood will be easier to get airborne than a 3 wood, all other things equal, just as a 9 iron is easier to get airborne than a 5 iron. If the goal is more distance through higher ball flight ALONE, then make the head switch and be done with it. However, if MAXIMUM distance is the goal, then abandoning the 3 wood for a 4 or 5 wood makes no more sense than putting a driver-length shaft into a lob wedge head; it would go really high, but not nearly as far as one might hope.
The reason is that the more lofted head increases backspin, while the shaft change can increase launch angle with low spin and yield better overall distance because of more roll. OVERALL distance is a combination of carry and roll, of course, and well-hit 3 woods go farther than well-hit 4 or 5 woods, don't they?
The trick that was being asked about in the first place what how to get a 14* 3 wood airborne more easily; the proper shaft is the best way. A good clubfitter would make short work of this, providing the player is skilled enough to hit woods off the ground in the first place, which I believe Carey L. is.
