Would it be possible to remake Gone With The Wind today?

I’ve been amusing myself re-reading Gone With the Wind.  The racism in the book is undoubtedly offensive, but it is otherwise a rip-roaring, fantastically good story, whether as a character study (and Scarlett’s quite a character), as a romance, or as a portrayal of a culture falling apart in war and then trying to pull itself back together again.  My problem when I’m reading is that I’m unable to separate the characters in the book from those in the movie.  When I read about Scarlett, I can’t stop seeing Vivien Leigh in my mind’s eye.  Rhett?  Clark Gable, of course.  Melanie is the lovely (too lovely by the book’s description) Olivia de Havilland, while Ashley is forever the badly miscast Leslie Howard (too old, too British).

My question for you:  Putting aside the fact that a story as racist as GWTW would never be made today, I’m wondering whether it’s even possible to imagine remaking the movie today with any of Hollywood’s current crop of known actors?  Can you think of anyone out there who could fill those shoes?
