If it is done RESPECTFULLY, I think that sending back the SEs could be a simple yet effective idea. It may not radically change things, but it will send a message, but since so few people are involved, it might not do much. Remember repect. Here's a personal favorite, straight, polite, and to the point:

"We want you to be aware that we have no plans-now or in the future-to restore the earlier versions."

Then I have no plans, now or in the future, to purchase any future Star Wars and Lucasfilm DVDs, magazines, comic books, action figures,model kits, video games, toys, or any other products ever again until the originals are properly restored.

Simple but effective.
