Gunfight would be a great addition, but i was also hoping Groundwar would make a return. It was some of the most fun I had in MW2 and seeing it return in BO6 would be awesome. Hopefully in the near future.
You say Outlaws is a vast improvement over Jedi: Survivor and Fallen Order but how further from the truth could that be? A more linear experience will always beat out a shallow open world with repeat quests and same old objectives. Both Jedi games are phenomenal and I doubt Ubisofts Outlaws holds a candle to either game.
