I think what is more likely to happen is the top European leagues get more champions league places, they already made it so the 4th place team dont have to qualify anymore, next time it comes up again in 2021, they will announce that the top 4 leagues (England, Spain, Germany and Italy), will each get 5 places and their teams wont have to qualify got the Europa league, so each country will have 8 teams in the group stages across the Champions League and Europa League. This will mean that teams from smaller nations will have to go through more qualifying rounds. But it will give Uefa a product worth more to television companies, as their will be more high profile games. I think they will also try to move the semi finals to the weekends.
