I think the blue ray release might blow all your efforts down.
I kinda remember my grand brother reading me an article at the time of RotJ when I was young reporting that Georges Lucas was developping a "blue laser" technology for the future. I also "kinda remember" this was stated in "STARFIX Hors Serie n°1 - Le Retour Du Jedi" in France.
I also remember GL didn't want to release Star Wars on DVD at the origin because he waited a better format to be available.
And I finally remember the fake RotJ title: "Blue Harvest"...
Secret Plans ?... Sorry to say, but I think you're all going to be the big "blue harvest", guys.
