And you could even switch it up so that you use the Luke contacting Leia scene for his Crait projection, have Luke live, then you show him hovering above the rock when he is moving the Raddus, and THEN he stares at the binary sunset to end the film.
Sadly darthrush, Luke is wearing his dark costume in that scene where he ‘makes contact’ with Leia from his island - so that would be quite jarring if it’s mixed with his white robed scenes in this way.
