You'll probably have to make a mod for it so that any new Gal Civ 3 updates won't overwrite your changes. That being said, I found the xml sheet at C:\Program Files (x86)\Steam\steamapps\common\Galactic Civilizations III\data\Core\UISizeDefs.xml for the scale of the UI itself (though not specifically for the mini-map).

As far as I am aware, the topic is a bit hush-hush on exactly what you can do when altering the galaxy. However, I do know that there is the potential to help specific alien species grow or shrink depending on the actions you make, or in some cases, the inaction. I know for a fact that some races will have their borders shrink and wither with the passage of time. In addition, the more races you align with, the more ships will be moving to-and-from Earth.
