If you only swap it at the main plug like you're suggesting, then the color code gets all jacked up. Good luck to the next guy that has to figure out wiring hacks. I understand the desire to be lazy, but it's really not hard to swap two wires at each coilpack connector.

One cannot find any reference of wire coloring in official Nissan FSM. Only numbered pins from terminal to terminal. And that's the only correct way, in my humble opinion, to make wiring write-ups. Leads could be mixed up, color perception of different persons could be shifted, insulation could change color due to aging, etc, etc. That's why I'm pissed off a bit by "red wire to green, blue to yellow" manuals type.
