But seriously man they should have gone full Blue Thunder. Say that the Falcon has become this legendary ship that every shady character in the galaxy wants. Han won't give it up so he has to constantly fight off new challengers. Say that that's what caused his marriage to fall apart instead of Ben turning to the Dark Side. So he's off doing his free spirit thing until an evil smuggler/bounty hunter comes along that is every bit as good a pilot or better.
The guy kills Chewie leading up to a big mano a mano Falcon vs. the bad guy duel through the complexes of some big industrial planet. Han does some sweet maneuver and ends up blowing the guy away right through the glass of his cockpit then sets the Falcon down inside some massive trash compactor. He takes a last minute to remember Chewie and then exits, casually lighting a death stick and walking away as the Falcon is crushed and explodes behind him. Han walks over to a terminal and calls Leia, telling her he's coming home but that it will take a little while because "registered transports are hell." Her stern look on the monitor softens and then cut to credits. End Saga.
Boom.
