Plenty of opportunities for us (Monica's) to play such clubs in the league. Also, I believe it will make promotion and relegation more fluid between championship grades. It's very hard for a JAFC team to aspire to play SFC currently as they have to beat the 2nd and/or 3rd teams of bigger clubs to win the JAFC and IFC along the way.
I would advocate the introduction of a one club/one team, knockout championship as a secondary competition. Each club can enter only one team. They can use whatever grade(s) of players they like. Open draw, first team out drawn at home. Extra time and some sort of shootout to decide the tie winners, if required. No replays. This could be played mid-week during April and May.
