I know we have had enough champions cup formats over the years but what if we get all URC, Top 14 and Premiership teams so 40 teams and add another 8 teams from other European competitions giving us 48 teams. We then designate 2 of the other teams as top 14 teams and the other 6 teams at premiership teams. Then we draw the teams and make pools like the current ones. Then the top 2 from each group play in the champions cup round of 16 and the 3/4 placed teams play for the challenge cup. The bottom 2 teams play for the 3rd competition with the finals of all three played at the finals weekend.
