Comparing Photos by image difference

In Lightroom compare two files in the x-y display by subtracting RGB values of the candidate photo from the selected photo. Result shown as image on candidate display or as separate image display. Simple (No dates & times needed, nor develop histories). Files should be synchronized. This would be particularly helpful when combining old catalogs into current one. No need to worry about file format or virtual  copies.
