It would change the dynamic of how the game is played. Less emphasis on passing and more on getting it into the box. You wouldn't need to unlock a defense as you could by pass it. It would be a different game alright.

To be fair a lot less whistling and some consistency across matched would go a long way to improving the game and making it more watchable. That and referees not taking shit from the players anymore. Simple things that would improve the game immensely.
