Which BG1 NPCs are available via mod?
 

...and which mods are they? ...and where can I find them?

I think I remember seeing a Kivan and a Yeslick somewhere, and I know there's a Xan mod as well.

Any others?

The mod sites I visit most often are Pocket Plane Group and Gibberlings3. They probably have links to others mod sites as well. Go to those places and shop around.

The Xan mod is extremely well done, and hte kivan mod is wel done, albeit with no voices for Kivan last I checked, and the Yeslick mod... well... not so much.

Kivan of Shilmista and Xan are both full-fledged mods, and from what I hear they're well done. Xzar and Montaron are technically both available as part of Dark Side of the Sword Coast (or something), but none of the NPCs in that mod have any banters or quests, and the mod as a whole is somewhat buggy, I hear. I've never heard of a Yeslick mod . . . which isn't all that surprising, considering the depth of his personality in BG1.
