The 30 Scottish Football League clubs have unanimously voted to propose a new three-tier league structure of 16, 10 and 16 teams for season 2014-15, reports BBC Sport. Its top-flight would be called the Premier Division, the second the Championship and the third would be called the First Division.
The plan involves a merger between the SFL and the Scottish Premier League.
SFL chief executive David Longmuir's plan would require agreement from the SPL and the Scottish FA.
Following a meeting at Hampden, the SFL is also proposing a new format for the Scottish League Cup based on a seeding system similar to the Champions League.
However, SPL sources have suggested there is no prospect of the SFL plan receiving the support of the 11 clubs required for such change to be accepted by the present top flight.
