Thorns + bucc with no stun mastery = bossing bucc?

Thorns works so long as there's no passive critical, and stun mastery doesn't work without stun. It's best just to ask someone to test it in kMS.

Coding wise, the way i see it, stun mastery is basically just regular crit with an if condition stating that the monster must be stunned. Just because bosses can't be stunned doesn't mean stun mastery isn't still there.

The statement "Thorns works so long as there is no passive crit" only holds ground until used on buccaneers (the only class with condition based crit), which results in thorns needing a new definition. There isn't any proof of a bucc critting without stun when thorns is active.
