Arguably the one known character who should have a recurring role should be Paul Sun-Hyung Lee’s pilot. Maybe the different series could use a Coulson-like character to add up interconnectivity in small doses but it’s time to let each storyline breath.
I forgot to mention him, but yeah! Paul Sun-Hyung Lee’s enthusiasm for Star Wars and happiness at appearing in it is infectious and I’d love Carson Teva to appear in more upcoming projects for this alone.
In terms of story reasons, it’s well worth focusing on people who’d usually be background characters, viewing the struggle of the New Republic to succeed the Empire from the perspective of a ‘random’ x-wing pilot.
