Well, since we're talking aberrations and lawsuits and playoffs, may I request more NPC conversions from other games, or at least lookalikes? There's plenty of great NPCs available from the CODI packs, but the problem is, as neat and high quality as those are, they don't exactly work as overrides for already existing models. The rangers included in the CCC proved high quality models can work in good old NWN, same as Draygoth's drow and duergar. There were also these Gothic 3 armored guys which, aside of broken shadows, look awesome in the aurora engine. Fable armored NPCs? Got them!
Also, heads. Aside of the KOTOR heads by Estelindis, and a few other works, there is a lack of high quality heads, for both genders. I think model conversion would save us here as in pretty much any other model-related absence. Don't know much about it, but I would think conversion is much easier than building something from scratch.
Now, with all this zombie and undead talk in the forums, I thought it would be cool if NWN zombies looked like Skyrim's Draugr; you know, skinny, armored and with eyes flashing? The Draugr are pretty much zombies and, in my opinion, have a better appearance than most other renditions of zombie-like monsters. It's my own view, but I always thought monsters you encounter should scare you to death by their looks alone, not make you think of cartoon characters drawn in children books.
Finally, cows. One of the most used animals in modules are cows, and they look so terrible.
