To make an extreme suggestion, we could move the three-point line back 5.25 feet to 29 feet. Eliminate the corner-three exception, the line would be a literal circle, and in this case would intersect the sideline just a hint closer to the baseline than the free throw line.
This would make a lot of people angry, as offenses are designed to utilize the corner three, and a corner two is a much different thing. In fact, a lot of modern offense - designed to get high-efficiency jump shots - would be nearly useless. But I imagine it would make Slim very happy (he could be happier, but we're not eliminating the three-point shot altogether in the near future in any imaginable timeline).
