My super professional answer to Will Ben Solo come back - maybe, if they want to.

Mythologically speaking slaying the dragon is often personified with destruction/death of the body.

How the heroes journey continues is now up in the air. But despair for the loss of the hero is significant and in someways vital according to Campbell.

the heroes return imparts the mystical and transcendent experience like the ressurection of Christ or the return of Osiris

But it will only happen if they want to take the heat for saying it was the end and making it not the end.

So i don’t know. All I can say is the mythic parallels are there. The story could be told, but it will depend on the teller.
