No, but that's only because the concept didn't exist back when he was doing the when George made both the OT and PT. Back when he made the two trilogies the international market was only a very secondary consideration and the studios were focused heavily on the domestic box office. Nowadays, the overseas market, China, in particular, can make or break a movie and I realize that it's hard to believe but movie studios are in the business of making money so, of course, they're going to do things to not piss off the overseas market.
Would George have allowed changes to his movies or their posters in order to appeal more to China and the overseas market? Hard to say, but lean towards yes given how much he's tweaked the OT over the years.
