No need to proof, I know it works if the key B = A and C = A. However, I don't know of any tool doing this. Also there are other (more interessting) attack-vectors on 3des, but all of them require to do something wrong with handling 3des in the first place. There's no general error. Anyway, based on your stated purpose, I don't see a use for this in hashcat.
