Switch Smooth Follow between targets smoothly

I'm not happy with the code below, but it is all I have time for at the moment. It's based on the standard Smooth Follow. You need to Lerp() both the position and the LookAt rotation in order to get the smooth movement you want. Of course this will impact the general movement. Try it an let me know. There is another way to approach the problem (that does not involve modifying SmoothFollow).

 var target : Transform;
 var distance = 10.0;
 var height = 5.0;
 var rotationDamping = 3.0;
 var movementDamping = 1.0;
 
 function LateUpdate () {
     if (!target)
         return;
     
     var wantedHeight = target.position.y + height;
     var currentRotationAngle = transform.eulerAngles.y;
     var currentHeight = transform.position.y;
 
     currentRotationAngle = target.eulerAngles.y;
 
     var currentRotation = Quaternion.Euler (0, currentRotationAngle, 0);
     
     var pos = target.position;
     pos -= currentRotation * Vector3.forward * distance;
     pos.y = wantedHeight;
     
     transform.position = Vector3.Lerp(transform.position, pos, movementDamping * Time.deltaTime);
     
     var q = Quaternion.LookRotation(target.transform.position - transform.position, Vector3.up);
     transform.rotation = Quaternion.Slerp(transform.rotation, q, rotationDamping * Time.deltaTime);
