At first they should reform current system that cup winning ticket is NOT punishment in continental leagues for weaker countries. Currently cupwinner must start from later round and has no chance to get opponent from similar level as they all lost already in previous rounds. That system was abandoned by UEFA on 2013 something.
When creating third cup to Europe other continents want it too. But most of European leagues have just 4 tickets to eurocups when weakest country from some smallest continents has 6 or more tickets. Conference League did not give any additional spots to countries just smaller clubs from EL preliminary rounds were moved to new cup plus ChL clubs who had early exit. Currently South America and Oceania don't have many clubs in preliminary rounds and third cup for them will mean more continental tickets when most of their clubs are already guaranteed to group phases.
Main problem ofcourse is that nobody is doing it until Vincent will sell game to community.
