I don't see defeating the Night King on wight-Viserion as that hard; not if the Targaryen Air Force develops some proper tactics, at least.

Wight-Viserion can be damaged to dysfunction with conventional weapons, and destroyed with dragonglass. We haven't seen anything that suggests the Night King is invulnerable to dragonglass or Valerian steel (yet). Team Targaryen has lots of dragonglass now.

Set a flight of two Dothraki Longbow Dragonfire Gunships(TM) against him. Rhaegal has Jon as a pilot, and carries two Dothraki archers. Drogon, with Daenerys, has four archers, and a small ballista.

Jon flies a pinprick raid, and taunts the Night King into following him along the coast. Now, they are both ahead of the army of the dead. The Night King is behind enemy lines. Daenerys picks up the chase, and gets on wight-Viserion's six-o'clock. Add some ballista rounds from Targaryen ships, just offshore.

The Dothraki arrowheads, the ballista rounds are all tipped with dragonglass, of course.
