I can second most of these, except that I love Doc, b/c Bruce Campbell.
We need moar choices for LI's though:
Tallos Drellik (he's adorable, yes, he's dweeby, but he's adorable)
Doctor Lokin (The Most Interesting Man/Rakghoul In The Universe)
Blizz (you know you want to)
What's wrong with Broonmark? He is such a deep character; clearly one of the more well-penned personalities of this game (and not psychotic).
