The thing is the Gout is already altered. Grain removed by process of dvnr. Letterbox 4:3 instead of Anamorphic, not the original techniclor, colors are faded. Not the theatrical sound mixes.
Their is nothing original about it. Its does not even make a Close Approximation of what people saw in the theater in 1977, 1980, or 1983. Except it does not have cgi like the 1997 or 2004 versions.
Lucas did a cut and paste Job on the 2006 A new Hope bonus disc by adding the non a new hope crawl to the beginning of the movie in hopes of tricking people into thinking it was the original release.
But that did not cost him any additional money since the opening star wars crawl was already telecined for the Empire of Dreams documentary. Therefore proving he could go about undertaking an entirely new anamorphic telecine of the originals, except he does not want to.
