Heya. We are working on a mod for BG1, one that will add banter and depth of character to the NPCs.
If you're interested in this idea and esp. if you're interested in helping out in any way (large or small), feel free to go here:

(then scroll down to ->Infinity Mods ->Infinity Engine Mod forums ->BG1 NPC Project)
We could use more team members and any help you wish to give. Help with dialogue writing and 'idea' people needed esp (no tech knowledge required).
