It's never worked. The old adage, when you have two starting QBs you have none. The QB is the focal point of the game. An OL learns their tendencies and preference, timing needs to developed with WR/TE's, it's just too difficult. It's why the wildcat will always be a gimmick used to surprise.
If Kaepernick is the guy he needs to stay the guy and Harbaugh better hope they don't run flat into a wall. By making the move he may very well have thought a wall was coming regardless. One other variable is they have a good defense to help cushion any stumble that may occur.
