Is it possible to fade seemlessly from one skybox to another?

Hi gang! making my start game ingame cutscene have my Rocket going into space and want to fade from one skybox to another to create a seamless transition into the game.
somthing like this
using UnityEngine;
using System.Collections;

public class Launchskyboxchange : MonoBehaviour {

	public material Skybox1;
	public material Skybox2;

	public float ChangeSkybox = 12f;
	
	// Update is called once per frame
	void Update () {

		// Fade skybox over time (fade materials.)
	}
}

You can achieve this by designing your own shader with e.g. Shader Forge. There you can create a skybox shader and then you could simply fade between two skybox textures.
