Why doesn't CCP allow UI modding like Blizzard? The UI has lots Of room for improvement. Eve seems to have a very technical Player-base as well that would be up to the challenge.

CCP would have to do a major rewrite of the UI to make it moddable like Blizzard's. It would be a major development effort, it would almost certainly introduce bugs and exploit paths that CCP would then need to fix over the course of several months, and CCP's developers are already rather stretched, working on new features (such as Incarna) and trying to fix the bugs that most of the player base is complaining about (such as lag).
If you want CCP to focus on creating a modern, moddable UI for the next expansion(s), you should probably start by convincing the CSM - they are your elected representatives and are supposed to have some influence on the direction of Eve development.
