For the record (because reading the write-up I wasn't sure), when Radzkie said that your faction could be affiliated with the Galactic Alliance, he didn't mean that it would be a subfaction or an "official" GA subdivision. The difference is that your faction would not be solely responsible for the purpose it fulfills - there would be other 'criminal investigative services', and you would not be responsible for all of the Galactic Alliance's criminal affairs.
