Adding a K-2 droid to the background of a scene in the Death Star isn’t at all “adding random nonsense” like Lucas did.
You could say that the battle droid Ady added to the sandcrawler is closer to that kind of tinkering, and even that isn’t the same at all. These small changes can help thread the galaxy together.+1. I consider this a very good suggestion. Might be hard to pull off but I have quite the faith in Ady.
+1 this idea as well. I think it makes sense and would add to the continuity of the universe.
