Just say Mac or putney beat west penno in the semis and make the grand final against bats. 
Would this be the first time in history a team has forfeited a gf?

If Putney or Mac beat WPH (a big ask, admittedly) they will almost certainly qualify for the GF against Bats and will be a disaster for the Association. 
Watch for some favourable refereeing in those games for WPH

Imagine suddenly men aren't allowed to play in the women's comp for the grand final (wild thought I know) and the bats team get smashed 100-0 coz the actual females are all shit
