I don’t think any of that is in the final, film, though. We barely ever see Leia holding the medal, and it’s doubtful most people noticed what she was holding. I don’t think there is any indication that Leia is responsible for the vision of Han in the film. Even Adam Driver in the BTS seems to imply it is mostly in his head, and not Leia projecting his image to him.
You could have Leia say something else more than just “Ben” as she’s dying. Like, “Come home.” This way, Leia, Luke and Han all play a part in saving Ben.
And, for edits that might have Ben live in the end, I imagine that many versions will have Leia play a part in saving his life.
