Welcome to TresCom!
The majority of mods ever released for this game have been based on peoples own ideas, cause that has been what people want.
It is possible to update the dinosaur models but then again, there has been little demand for a mod like that over the years.
Trespasser does not use animation for the AI, which makes it a lot more difficult to fix. The source was leaked a long time ago and the best we got from it so far is the CE patch. The code is complex, and even the devs say you are better off making a new engine from scratch than trying to fix it. And we don't have that many people who knows coding in the community, let alone be able to fix or improve the AI. It is worth remembering that games still today don't try to do the AI system Trespasser has, with emotion based AI, and not animation.
As for improvement over the retail. There is a HD AI texture upscale mod. Otherwise something like Trespasser: Isla Sorna is trying to fix (what we can fix) in the original levels, as well as combining them with the earlier versions we have and combine some levels to make them bigger!
