The potential for the top flight to have 16 teams was among a package of reforms announced by the game's three governing bodies, ahead of Friday's vote by the Scottish Football League clubs on whether Rangers newco will play in the First Division or Third Division next season.
The Scottish Football Association, the Scottish Premier League and the SFL issued a joint statement outlining the proposals which would see the SPL increase to 14 teams for the beginning of season 2013/14, with a mechanism in place to add two more at a later date.
Changes to the size of the other leagues as well as the merging of the ruling bodies, the redistribution of monies, parachute payments, play-offs and a pyramid system are also on the agenda.
The reforms are a carrot for SFL clubs to vote the Ibrox club into the First Division, a decision which would, according to SFA chief executive Stewart Regan, save the game from financial catastrophe.
Houston told Sky Sports: "I am not against it. We would need to get something sorted out that looks attractive.
"There are some clubs who are in the SFL who are big clubs in many ways, who spent a lot of money getting all-seater stadiums when they were in the SPL.
"They spent that much money they probably couldn't enhance the team on the pitch which means they couldn't get back up.
"It has crippled them in many ways so if it is a bigger league and clubs are going to earn a wee bit more money then that's great and it might bring a freshness to the game."
