P.S. It's better to unite 5 groups in 2 with 9 teams in each one (4 best teams in each group go further), in my opinion. So that will be more interesting tourney, cuz all teams will get more chances to pass the group stage.
So it'd be like 8 matches per team, just for the group stage. Too long imo, it would take ages to complete the tournament.
1) Not longer than NWL, NLC or RGL, cuz 1 match not take longer than 20-30 minutes unlike NWL's lb
2) That works unlike the table with 5 or 6 groups (number of groups has to be 2*n)
3) NWWC is an annual cup so every country wants to play more than 1 or 2 matches in such tournament.
4) Organisers will not have to change the brackets but just unite them e.g. A with B and C with D.
So, at the beginning offer your idea before to criticize someone, suka.
