72 might actually work, even if the structure becomes a bit complex ahah
The bottom 26 teams get divided into 2 groups of 13 and play each other once... with a couple of promotion spots up for grabs... like the top 2 of each group or something like that
The top 72 would instead be divided into 18 groups of 4
We can call this the “qualifiers” for the "World Cup"
Top 2 of each group advance, bottom 2 go to the “losers” side
Main phase:
6 groups of 6 (made of 3 first-placed teams and 3 second-placed teams)
Same structure for the losers: 6 groups of 6 with 3 third-placed and 3 fourth-placed teams
From there:
• Top 2 of each group → Gold phase
• 3rd & 4th → Silver phase
• 5th & 6th → Bronze phase
(and same for the losers’ groups)
Each phase then has 2 groups of 6
And at the end you can do semis + finals... or just a final
In total it gives everyone
3 games + 5 games + 5 games + semi/final.
Although a bit complex it would be fun

Tho I don't think a change to the NT world is coming anytime soon
