I hope I'm not the one that brought this on. ;)
Honestly, while Dungeonland was well-done for its day, I'd probably skip doing adaptations of an adaptation and simply adapt Alice in Wonderland and Through the Looking-Glass directly. The Advanced Race Guide can help with tricky characters like the Caterpillar, the Frog-Footman and of course the March Hare; re-skin a blink dog (and alter its alignment) and you've got the Cheshire Cat. Designing the White Knight as the world's least-effective Cavalier could be fun...
Hm, this may be a fun enough project for me to tackle myself. Perhaps my characters can plunge from the dreamscape they're currently exploring into Wonderland as a detour on their way back to the 'real' world.
