I want to bring Legion to Tali's hearing and also exhaust the dialogue for all squadmates. How am I gonna do this?

Is there a way to bring Legion to Tali's hearing while also completing Legion's loyalty mission before the suicide mission? Iirc after doing the Reaper IFF you have 1 mission you're able to do before the Collector abduction, so wouldn't that only give me time for one loyalty mission, meaning I could bring Legion to Tali's hearing but I'd have to skip Legion's loyalty mission?

Also, if I save Operation Firewalker for post-game content, would those 5 missions be enough to hear all of Legions dialogue?
