Of course. Perhaps even an episode where someone from the future travels back to destroy the NX after having caused harm in Rikers time. The Titan comes back to stop the plot and works with the NX to do it. That or vice-versa: Archer learns of a plot from someone in the past to attack Riker and the Titan in the future. He travels forward, with his vastly inferior ship, to try and stop it.
Either way, it sounds far, far better than TATV.
It sounds like a retread of the Temporal Cold War™
