Option 1
I think Elaina Beneski, like all of her close friends, is ultimately an agent of chaos, so any rule changes made at her behest will ultimately reflect that. Let's be honest - no one ever had their life become more stable when Elaina, Kosmo, Giorgiy or Jerzi was introduced to them.

First rule change - Second period goalies are pulled. On the surface, this looks like a true chaos option, and indeed I suspect it may prevent repeating, but it's ultimately going to force fundamentally sound hockey. You have to back check without a goalie. You have to play tight defense without a goalie. Every shot counts, because every shot is a goal.

Next change - all players must be deemed sponge worthy.

Last change - enlarged shoulder pads. What can I say? Elaina is a true 90s girl and she loves her 90s style. Everyone has to have those big Klingon style shoulder pads for some reason.
