The document was reportedly leaked to Scottish media by lower-league clubs infuriated by the SPL's high-handed attempts to get their own way.
SPL chiefs want Rangers to be sent down one step to the First Division as a punishment for their years of gross financial mismanagement, but several clubs in Scotland's second tier have already insisted that they would block any such move.
The leaked document proposes a merger between the SPL and the Scottish Football League, which would bring in end-of-season play-offs and a new financial distribution model for teams in the top two divisions.
If that plan is rejected, however, the document threatens the creation of a new 'SPL2' division, which First Division clubs would be invited to join alongside Rangers. It would then operate as a closed system, with no means of getting promoted to SPL2 from the lower divisions.
SFL chief executive David Longmuir confirmed on Thursday that a briefing document was to be send out to clubs which he described as "a logical and positive communication which will hopefully eliminate some of the understandable doubt, threats and insecurities that are apparent within the game at the moment.
"The consultation document will fully explain the short- and long-term benefits of a number of scenarios which we will be considering at a full club meeting next week.
"The Scottish Football League is trying to address the question of whether we are in a position to accommodate a solution to the Rangers FC scenario. We are trying to achieve a solution which will be in the best interests of the Scottish Football League and the wider game."
