As others have touched on, the reason games are longer now is because of more commercials (more pitching changes and longer commercial length), higher counts as batters see more pitches, and far more periods of time where batters are stepping out of the box and pitchers are stepping off/walking around the mound.
These rule changes do nothing about pitching changes and higher counts, and you're likely not going to do anything about them. Thus, yet again, the issue is not with the rules, but with the way umpires enforce things. Just make sure the umps are getting people back in the box and set, ready to go, more quickly. That's literally all it will take.
