Before you actually do that, you might want to think about if it's a
good idea or not. Are you trying to deliberately mislead or confuse
your readers? If so, it's a good idea, otherwise it's probably not.
You might want to read this "blast from the past":
K. W. Haemer. Double scales are dangerous. The American Statistician,
2(3):24–24, 1948.
