hmmm... the ratio cups to champions leagues is 7:8
the ratio of leagues (excluding level 1) to champions leagues is 2:7
ratio cups to leagues is 7:64
A "block of clubs" is 896, 7 cups, 8 champions leagues and 64 leagues
Of 896 clubs, only 256 play in the champions league each season.
For the ratio of cups/champions leagues to be changed to 1:1, the number of clubs in each league would need to be expanded to 16.
