I have this french 1977 version of the comic book. :)
I could make french and english subtitles .srt for this edit. But, well, I'm lazy when it becomes to work again on an old fanedit.
I usualy make subtitles for my newest edits. Mostly always french, because I'm french, and english because it's easier for everybody to follow the dialogue if you're not english speaker.
About new dub... well, yeah, it would not only need new dub for the deleted scenes (the french SE already have new Han Solo's voice actor on the Jabba scene though...) but it would also needs to find new voices by the same french actor who makes JEJ's voice, for Vader. And since I used some interviews and speach of JEJ that are not on any movie, it could be difficult to make a true french version of this edit.
