Except it can’t be Ochi’s ship because it’s on Pasaana…
Not necessarily, the ship could have been repaired and used again by ochi until it found its final resting place on Passana. Turning Passana into Jakku would be the cleaner option, thematically it would tie Rey’s arch pretty well with her discovering who she is on her home planet.
Wonder if some downed Destroyers can be inserted in the background to really sell the idea.
