I don't see how this would help. For instance say the only lines in a book were: 1. d4 d5 2. Nf3 1. Nf3 d5 2. d4 Now if you deleted the second line, and your program was playing black, and white moved 1. Nf3 - it would start the search. (and may or may not choose 1...d5) Both lines transpose to the same position, but that doesn't mean you can delete one. Maybe I misunderstood you, but I don't think your idea would work if implemented.
