International Cricket Council officials, eager to freshen-up the longest format of the game, are considering a two-tier system which would include promotion and relegation.
The development is also likely to open up places for Associate countries currently led by Ireland and Afghanistan.
The proposal, if agreed, would place extra importance on the next Intercontinental Cup, the ICC's flagship First Class tournament for non-Test nations.
One proposal under consideration would involve the winners - or both finalists - of the I-Cup playing off against the lowest-ranked full member(s). The ICC's executive board will consider changes at a meeting later this month and is expected to move ahead with the plan.
Scotland finished third, behind winners Ireland and Afghanistan, in the recently concluded I-Cup. The next event is scheduled to start soon after the 2015 World Cup.
