The halo universe is fighting wars against more than one army with only tech that humans made from scratch. The troopers in halo can hit and do some damage. The other races are just super advanced life forms that will destroy the star ways universe. The halo rings would just destroy all the planets and living things so the clones and etc would not exist anymore. After the ring works only the energy beings like the promethiums would be left against the other star wars energy beings so it would basically turn into a fight in a space between halo and star wars races.
