How can I delete the Main Camera using a script?

So I'm attempting to create a wizard that will create a totally empty scene before it loads a default scene (which already contains a modified main camera) using EditorApplication.OpenSceneAdditive(defaultMap);

My script (provided below) generates the following error:

Can't remove component.

Can't remove Camera because GUILayer, FlareLayer depends on it

So how can I go about deleting / removing the dependancy between the GUILayer and FlareLayer? Will these things come along with my default scene?

using UnityEngine; using UnityEditor; using System.Collections;

 [MenuItem ("Wizards/Empty Scene Wizard")]
 static void DoWizard() {
     ScriptableWizard.DisplayWizard("Empty Scene Wizard", typeof(EmptySceneWizard));
 }

 void OnWizardCreate() {
     EditorApplication.NewScene();
     DestroyImmediate(Camera.main);
 }
