Unity3D: Convert all game objects to same size irrespective of it's scale

Untested, and completely from memory, but something kind of along these lines should work. I'll test it tonight when I have access to Unity.

//scales all GameObjects in goResizeList to have the same size as the referenceGO.
public void resizeAll(List<GameObject> goResizeList, GameObject referenceGO){
  Vector3 refSize = referenceGo.renderer.bounds.size;

  foreach(GameObject go in goResizeList){
     float resizeX = refSize.x / go.renderer.bounds.size.x;
     float resizeY = refSize.y / go.renderer.bounds.size.y;
     float resizeZ = refSize.z / go.renderer.bounds.size.z;
 
     resizeX *= go.transform.localScale.x;
     resizeY *= go.transform.localScale.y;
     resizeZ *= go.transform.localScale.z;

     go.transform.localScale = new Vector3(resizeX, resizeY, resizeZ);
  }

}
