Before I go on, there are a lot of playbooks available for Dungeon World. It is such a lovely and hackable game. And while your campaign may not have room for all of these playbooks, it is always interesting to see what is out there.
They most certainly would have a place in a Dark Heart of the Dreamer campaign, a Dungeon World love letter to Planescape.

- Templar - smite the heretics and drive your allies to push even harder for your cause
Individual Playbooks at DriveThruRPG
I believe all of these playbooks are under some Creative Commons License, which means they are yours to tweak and modified and even redistribute. Though some may come with DriveThruRPG watermarks.
You'll also want to checkout what bundles are available.
