As I've mentioned above it could work in two phases. The domestic phase and the international. Each looks to go to 3x6 teams domestic structure in the first plus finals. That's 12 weeks. Then in the second phase combine the three while including the three PI's and three other teams into a two 2x6 Cup competitions playing a single round robin for 5 games each with the top 2 from each going into the finals. All up 8 weeks.
