Ditto. I was quite well prepared to say that 4-5-1-2-3-6 was the stupidest thing I'd ever heard. I probably won't watch the prequels ever again, but if I did, I might give this a try.
Actually, maybe it's better I say it like this: I like the idea of this. Maybe if the prequels were 'good' or 'watchable' I would watch them this way. Your logic is pretty interesting, and keeping Han on ice a little longer and separating the Death Stars sounds good, but other than that I don't see the PT, as currently constituted, enhancing my enjoyment of the OT, regardless of where or when they are watched. They're just not worth watching to me.
But good job- almost thou persuadest me.
