Launch window from heliopause to Earth?

Assuming an ion propulsion ship was leaving station in an orbit at the radius of the heliopause, and the most direct trajectory takes 18 months to get to Earth, would there be a launch window or could the ship leave at any time? I was figuring with that distance, and time to alter the flight path, a ship could leave anytime and adjust its acceleration for an optimal flight time to Earth.

My assumption about flight time is based on this chart. Propulsion method and flight times throughout the solar system

I used the Ion B drive time to Pluto of 238 days as my starting point, an exaggeration, but not extreme.
