Or how about, as ric suggests, a discworld d-mod? Vilius is doing the Hobbit and The Lord of the Rings, whichc could prove interesting. Why not even a conversion (simplified of course) of say, Baldurs Gate? Maybe other D&D modules, such as The Veiled Society, could be converted well.
While I'm thinking about it, D&D is a brilliant resource for Dink. You could make a game with more stats to cover all the D&D ones, or just use a setting, such as the Forgotten Realms, or Dragonlance.
There is a wealth of monsters just waiting for someone talented like simonk to convert to Dink, not to mention the choices alignment could create.
A very detailed character creation process, with multiple races, classes, skills, weapons etc! I can't cope, the prospect is TOO fascinating. A bit over ambitious I suppose, but hey! Someones gotta do it!
