That would have the opposite effect. Round robin only favors those already stablished. What we need are regional tournaments and cups, both inside of Brazil and in South America.

For Brazil, reduce Série A to 18 clubs and 3 relegations, then create a level above the state leagues, using the CWC format. From time to time, invite teams from other countries to play in it
>Copa Verde (+Bolivia, Venezuela)
>Copa Nordeste (+Ecuador, Paraguay)
>Copa Rio-São Paulo (+Argentina, Portugal)
>Copa Sul (Uruguay, Argentina)

For South America, do something like
>Copa Gran-Colombia cup
>Copa Cone Sur (Chile, Paraguay, Argentina and Uruguay)

This way, every year there will be a bunch of teams winning different trophies, as well as a ton of higher level matches.
