Is there is a relationship to MyShelf so you could create a quick action on the Myshelf Items list and delete the entries. Once an Incident is closed a trigger business rule call the delete quick action using the run for child method.
Please test in staging as I haven't and not sure of the full ramifications of doing this.

Create and "Un-pin" Quick Action in Incident with the "Run for Child" Action Type and then create an action in MyShelfItem called DeleteWatchlist Item. Create a trigger action when Status = Closed that runs the “Un-pin” action.
The ShelfObjectId is equal to the RecId of the Parent object.
Thanks Paul. I was going down this route and trying to finish it up before I left for the week. This works like a charm.
