Let's be honest, we're struggling with a 42 team system, half the clubs aren't professional anyway.
Scottish Premiership (16 clubs)
>Aberdeen, Ayr Utd, Celtic, Dundee, Dundee Utd, Hamilton, Hearts, Hibernian, Inverness CT, Kilmarnock, Livingston, Motherwell, Rangers, Ross County, St Johnstone, St Mirren
To keep the TV sponsors happy, at the end of the regular 30 game season (winter break) the top 8 enter a straight knockout competition 'Premier Cup'. QF stage would be 1st v 8th, 2nd v 7th, 3rd v 6th and 4th v 5th to keep the top 2 (guess who) apart until the final, to likely add another Old Firm match.
Scottish Championship (16 clubs)
>Airdrieonians, Alloa Athletic, Arbroath, Clyde, Dumbarton, Dunfermline, East Fife, Falkirk, Forfar, Greenock Morton, Montrose, Partick Thistle, Peterhead, Raith Rovers, QotS, Stranraer.
The top 2 are automatically promoted to the Premiership, 3rd, 4th and 5th are joined by 14th in the Premiership in a playoff for the last spot.
This is where the Scottish League ends. Below it, the reformed Highland and Lowland feeder Leagues.
