100%.
i really think it’s as simple as initiating the Tier 3 league to run parallel to the current Men’s fall / winter schedule. Invite the top clubs from all three leagues to participate. Take the top ten, leave the rest. Force the issue. Then maybe these league will figure out how to work together.
Sounds good to me. Move the semi-pro season/tier 3 league to winter, with maybe some sort of summer competition as well and you'll build nicely. But has to be existing clubs with connections in their respective communities.
