Have never understood this theory that there will be too many meaningless games, along with not enough games over all.
A 16 team League, playing each other once at Home and once Away, giving a total of 30 matches a season seems to work fine in countries like Portugal, Russia, Ukraine and Greece. All of these countries have a far better coefficient that Scotland, and all of them have their national team at the Euro's.
We need to do away with playing each other 4 times a season, it has become stale. We need to do away with meaningless splits.
For additional matches, why not start the season off with the League Cup back in it's original format, with group stages. That would give all teams an extra 6 games at least. Have them played on a Saturday in July/August, a good warm up for teams in Europe too. All League Cup games fixed at a tenner. No Sky TV, just highlights on BBC/STV with the occasional live match. Get the punters in at the start of the season. Have them included in Season Tickets again. God knows this competition needs to be rejuvenated, the midweek matches just aren't getting the crowds in anymore. This would work well alongside a 16 team League.
A bigger League without any fancy split system would mean some less meaningful matches, but does that not give teams the opportunity to blood more youth players? We all know that's what has starved our national team for the past 15 years, too much pressure on too many teams to win the League/qualify for Europe/ get in top 6/fight of relegation meant that young players were rarely given a chance.
Just my opinion.
By the way, are they dead yet?
