If I had to bring one college rule over to the NBA, it would be making the "bonus" 1-and-1, and then super bonus for 2 shots. Not sure how they'd make that work with the NBA being quarters vs. halves in college but I love 1-and-1's I love 1-and-1's too, but I'm actually ok with the 2 shots in the NBA, largely because as you note there's no easy way to change it.
