Well, wouldn't it be best to take the Blu-Ray of I and II and edit it to match the AMC version, only leaving in the AMC shots when they're different? That way it's uncensored, and in the best possible quality.

The downside would be that the AMC logo, instead of always being there, would only pop up for extended scenes/shots, disappearing for the rest of the movie, which could be distracting.

That would be the way to do it, but obviously requires much more time and effort. Also the music would have to fit the scenes as well.

I've seen some samples of the AMC transfer, and it looks great. The AMC logo doesn't bother me that much, but the censoring of crucial scenes is kinda frustrating.
