Pretty much as the title says.
In the last week or so before a ship naturally despawns, have it 'drift' over to a ghost station (or other interesting place) to give it one last shot of at least providing some neat salvage or a second chance at life. (fully decomissioned of course)
Fairly low-effort way of creating a point-of-interest imo.
And would keep salvagers fed even during bouts of not much PVP
