I really like the idea of a massive coordinated showing of the Despecialized Editions in independent theatres, with voluntary donations going to support some cause nobody could possibly object to. Follow all the private showing rules: no concessions, etc.

Then, a week into it, switch from voluntary donations to a standard admission price, with 100% of it still going toward said charity, and start serving concessions. Whatever happens after that, from the best case to the worst case, we look good and Lucas looks like an ass.

EDIT: Convincing him is next to impossible, I agree. But public shaming is a powerful motivator, as is the fact that I suspect this could become hugely profitable for the independent theatres. And the large chain theatres may start asking where their audiences went, etc, etc...
