Because I seem to recall that there was a way back in the day. I swear I played as him once. Or maybe the mod and/or way just makes him a companion? Sheesh I forget.
About the closest thing I know of (I am by no means an expert) is to find Drizzt (won't work in the original BG1, but will in BG1EE and beyond), and Ctrl+Q him into your party. I would think you could then make him your leader and pretend you're him. He won't have a portrait, and I'd assume there are other limitations, but you'll hit your BG1 foes like a truck, and nobody in that game will be able to hurt you very much, if at all. :D
