Yes that makes sense.
To weigh in about the ranking system after the merge. Would you at least consider a 'reverse Utopia' system? All these managers are currently in D1. What I proposed for Africa was: make 2, 3 or 4 D1 leagues in this new country so they will have a season without cliff edge. Distribute the teams among the leagues based on World Ranking. The top 16 teams after that (by record, playoff participation or whatever other set of cirteria) will go in a single D1 from the 2nd season, the rest will all be demoted to D2.
This seems fairer to me. WR across nations is influenced by how top teams do in the B3 and since the schedule for that is random...
