Maybe he just wanted some upstanding citizen out there to see what it's like to be a dragon, hunted for money with no recourse to the law.
Aha! God, I'm so dumb not to have seen that connection.
In the Shadowtalk, especially in the Dragons of The 6th World, there is a poster (Dragonhunter?) who is not exactly quiet in regard to their distain/hatred of those big-n-scaley bastards. Words were said, feelings may have been hurt, etc.
It's not a leap to think that Dunkie, in his usual backhanded way, discovered the "Lead Hunter" and decided that the sauce was good enough for goose and gander....and it's a way in which he could have revenged his possible death at the hands of Dragon-slayers - something that strikes me as logical enough to fit. And even-handed enough to suit his sense of honour.
I mean, Dunkie did so much divination I'm sure he might have picked up a future echo from somewhere where he was blown up not by his own hand, but by a fanatical and savvy group of wyrm-haters.
And then written instructions in his will to suit.
Damn! Nice Plothook!
