Written option 1

Since the root of the problem is not having enough power plays, there would be two paths. Either we could have a lot more penalties but have them even shorter than minor penalties. Or we could have just a little more penalties, but ones that would be super long. Just for maximum chaos, I'll take the "little more, but long serving time". The rule then should be something that happens at least once every game. So, how about you get a penalty every time you fall over without any physical contact with another player. The official reason would be just "Falling". So any kind of a tumble that leads to neither skate blade touching the ice will net a penalty. And not just a penalty, but a new kind of a penalty: the 59-minute major. It's a penalty that leads to your team playing one player short until the last minute of play. That's when you get released. And the benefit at the end is not just that you get a rested player back, but all the players that were serving a 59-minute major can just hop on the ice. If your team has two players serving a 59-minute major, you'll play 7-on-5 for the last minute. To prevent situations where a team would intentionally start falling over at the 58th minute, this rule only applies in the first 50 minutes of play. If your team gets five 59-minute majors, the other team plays 5-on-0 powerplay until the last minute of play.
