How about finding some writer for a publication like Entertainment Weekly, or some entertainment magazine to get the full story out about the original movies. Get one of the magazines to do a cover story about the O-OT, and how they are stored away somewhere and can't be enjoyed on the latest format.
As much as we all want these movies out, I still think there is a huge amount of older fans who didn't really follow the prequels, and don't follow SW much anymore on the web like us, but loved the movies growing up, and really aren't aware that these versions either arent' out, or they have changed that much over the years.
But your idea is still worth a try!
