I wish Luke, Han and Leia would still be seen together in the ending.
Since it’s much more sad in hindsight in The Force Awakens, since that would be the last time they were together in a main movie.
Why not have the Ewok celebration, the planet celebration, the shot of Han, Luke, and Leia together, and finally the ghosts and then Luke by himself, in that order. That way, everything can still be there.
