Upon his reelection as World Rugby chairman, Bill Beaumont said that he would be looking at the introduction of a global season to the sport and the possibility of resurrecting the Nations Championship.
The annual cross-hemisphere competition was due to begin in 2022 but plans to introduce it died last year.
All Black second row Sam Whitelock believes the sport's governing body should not stop at international level with the notion of tournaments between northern and southern hemisphere teams.
The 115-cap international wants to see it in club rugby too.
"In general, aligning the world's competitions to open up these possibilities is a good thing," Whitelock told Newshub.
"You can imagine having the best northern v southern hemisphere clubs and international sides meeting every couple of years would be pretty cool.
"There is an appetite to see that - Munster v the Crusaders sounds pretty cool. There are options on the table, and we just need to work through those and debate them."
In a statement last month, European Professional Club Rugby - which organises the Champions Cup and Challenge Cup - said it has held talks with its shareholders regarding a Club World Cup. It was said the competition would complement current competitions and could take place every four years.
