Here are the solutions, IM not-so-H O: 1. One minute between half innings. The players hustle in, hustle out. Fielders need to be ready to take their positions. Pitcher gets 15 seconds to get to the mound then another 45 seconds to get his 8 warm-ups in then play ball. That's how it was up until about the 1970's. Double the price of a 30-second advertising spot and your revenue would stay the same. Advertisers will be willing to pay. The same for pitching changes. Get the reliever to the mound as quickly as possible using a golf cart or something. He has 45 seconds to get his 8 warmups in. 2. Pitch clock and batter clock, but only when the bases are empty. 3a. Larger strike zone. 3b. Lower pitcher's mound. Pitchers will be able to throw strikes more easily and batters will be less likely to try to work the count because there will be more strikes. The lower mound will reduce K's because the balls will be easier to hit, however this will be offset by the larger zone resulting in fewer strikes being hit well. Fewer deep counts, more balls in play, fewer K's, fewer BB's, fewer HR's. With these changes it will not be necessary to ruin the game by limiting pitcher changes or trips to the mound.
