I think they more likely cut it because it didn't make a lot of sense. Sure, Atris is a bad girl and could easily go DS (in fact, she does), but that doesn't change that "Fight the Force!" is Kreia's particular cause and not Atris'. It makes very little sense that Atris should suddenly adopt all of Kreia's goals and motives just because she became Darth Traya. I think that's why they cut it - Kreia's views and goals are pretty unique and cannot be simply shifted to Atris without credibility taking massive damage.
