It might be a bit more difficult for Galen and Rahm depending on who's facing who, but it won't change the overall outcome, even if its RotJ Obi-Wan, the fact of the matter is, Qui-gon is not a great duelist or a powerful force user. He was clearly competent in Ataru and could chain his martial arts along with his saber strikes, but, he's still a sort of weak link to Obi-Wan, and while Rahm himself has few accolades, most of them are impressive, he was able to hold his own against Starkiller, he was a proficient practitioner of Form VII: Juyo, and was quite adept at using Telekinesis. Which is more than I could say for Jinn. He would be defeated By Rahm whilst Obi-Wan is busy with Starkiller or the other way around if You want.
