My tuppence worth is that you are already fully aware of the dangers and the only "rules" being those you must comply with to keep Constable Plod happy.
I share your concern which I why I generally shoot them with a 12 gauge as any stray lead has a far shorter range which is reduced even further by foliage etc. Bloody noisy but safer in areas where there are others. My only other point is to know the lay of the land by day over which you are shooting at night, so to be confident that there is nothing beyond the possum which could suffer from that line of fire.
I am sure others will have worthy points to add
