I'm gonna go out on a limb here and suggest:
Archeologist. (Or, if you like, Explorer.)
This is a standard character from NetHack and I think he'd be well suited to DCC's hack-like theme and setting. As a point of reference, think Indiana Jones. "With a torch, some parchment and charcoal for mapping, and a trusty bullwhip, the archeologist/explorer goes to the remotest places, from the darkest depths to the highest peaks in search of rare treasures, artifacts, knowledge, or simply the pure thrill of being the first to make contact with an obscure tribe in the jungle. That is, if they don't end up sacrificed to dark tentacled gods or thrown in the cannibal's pot..." Sort of a combination of sage and thief, maybe a way to use Personality to generate helpful rumors / secrets.
Tinker. (Gnome, maybe?)
I think the best example is Data from The Goonies (though he's not a gnome). "The tinker is a cobbler or a cooper who simply can't stop inventing, refining, creating new contraptions. They can harness steam power and, sometimes, the wild and dangerous power of the lightning. Their machines are usually helpful in nature, but sometimes dangerous, even more so than the magical forces harnessed by wizards..." For those who want to steampunk-up their campaign some with airships and Ye Olde Blasterguns.
