I've opted to go with @zoelzw's solution in #28 since it seems a bit cleaner as stands, so I'm going to close this PR. But please feel free to file another PR against master if you feel like more clarification could be needed in this question. Just a quick comment on the .sty changes, I think I'd rather keep the styling of j more consistent with the book and leave it as an italicized j to represent the imaginary component.
