Halo Intro Video Idea

I just got this idea after finishing Halo 2. I let the credits to the game and the last cutscene of the game play. I was calculating my total campaign time when the intro video of the game started playing. (You know the video that plays when you don’t touch the controller for a while while at the title screen.) And I started thinking, what if in the next Halo game we can use theater mode to edit together a personal montage of ourselves playing the game when the intro video would normally play? What do you guys think?
