Mine is the same setup you are doing, port and starboard on the console and the white ona pole offset to starboard of the engine.
Whether it is legal or not that is the setup that was practicable and gave me the 1m seperation.
No doubt when the government finds out a light police will try and fine me for daring to be practical
I wouldn't worry too much about it, have you seen the number of small boats of all kind that do not have any lights at all? Some effort to comply is better than most!
