A Lucas written-and-directed ST would have probably sucked almost as much as the PT.

That's why I added "guest-directing" and "guest-writing" (read more closely) from a third director/writer :)

But I talked not about alternative story (original story with three additional episodes about Luke carrying on the quest of his twin-sister Nellith), but the story as it had crystallized by the time of finishing episode 6. To my mind it would be cool to watch our heroes after the death of the Emperor as the struggle to rebuilt the New Republic (but without Thrawn crap).
