If what I'm proposing is sound, then scrambling would also allow for re-use of one time pads on multiple files.
The whole point of a one-time pad is that it's information theoretically secure if you only use it once. If you don't care about that, then there are much better ways to encrypt things. If you use your pad on multiple files, there are chosen plaintext attacks that can recover the keys.
