Some states use a "past successes" formula where they can bump a team up a division. In the past the WIAA has discussed this option, but tabled it. This might be a fine idea. The other idea might be a tournament of champions. Like in basketball, why not put the top 5 divisions in a mini tournament? What's the harm? Hockey could have d1 and d2 play against each other too. Out in California they have an open division on top for the best teams regardless of enrollment. They use the past success formula too for the tourneys. Our daughter's basketball team was Div. IV but Div III at tourney time (and in a league with Open teams which worked out as you'd expect).
