Rugby League International Federation chairman Nigel Wood has "a degree of confidence" that a Great Britain Lions team could tour the southern hemisphere from 2019.
There has been no Lions tour since the representative side played a series in New Zealand in 2007, but Wood will travel to Australia with a view to firming up plans to end that wait.
Wood wants contests lined up starting from next year through to 2021 initially, with a proposal for New Zealand to travel to Great Britain in 2018.
It will also be suggested the Lions go on tour in 2019 and Australia head to Britain the following year, as well as increased matches between tier two nations and Australia, New Zealand and England.
Wood told BBC Radio 5 live's rugby league podcast: "That would be for matches against Australia, New Zealand and other nations. It's a real possibility.
"It's not a foregone conclusion, but I wouldn't be having this discussion if I didn't have a degree of confidence."
He added: "We want to give them [tier two nations] access to playing against England, Australia and New Zealand.
"We saw last year, for example, how spectacularly well Scotland did. But France have only played against Australia once in the last 10 years.
"There's a log-jam in terms of the aspirant nations that we're trying to improve and get stronger and put more quality and depth in the World Cup."
