My go to guys with this one would have to be Joe Johnston (Lucas, Spielberg, protege) for Episode VII, Thomas Alfredson (Tinker, Tailor, Soldier, Spy) for Episode VIII and Nicolas Winding Refn (Drive) for Episode IX.
For writers, I could see Steven Moffat (Doctor Who, Tintin, Coupling, Sherlock) as capturing the high adventure and high melodrama tone of the franchise well. Hell, it's a long shot but Lawrence Miles (Faction Paradox, Doctor Who) could turn out a cracking Star Wars screenplay.
