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.

You would think, this is exactly what I was thinking, not only would it be uncensored as you say, but it would be the best quality for sure, this is what I would do, strange.
