From your earlier statements, the precursors are just watching things unfold, so they aren't legitimate in the fight over which universe would win. They are basically pacifists. If there were to be halo rings existing in the Star Wars universe, it would be felt on both light and dark side. The light side would be forced to destroy the ring to preserve life and the dark side would seek the same objective to preserve the cause. The precursors would watch it unfold and wouldn't care either way, so please stop basing you argument on these pacifists of "gods"
