Drastic changes aren't needed. The rules just need to be tweaked to encourage efficient play. Not allowing batters to step out is one good idea. Excessive pitcher changes is a huge problem. Each change adds 3-5 minutes to a game. One thing I haven't heard mentioned is providing a way for catchers (teams) to call pitches in a more secure manner. Catchers go through so many signs just to communicate a pitch type while a runner is behind the pitcher. Each pitch could add an 5-10 seconds to hide the sign from the runner, depending on the scenario.
