What about getting all the reserve teams and top junior, east of scotland league and south of scotland league and highland league
I would have a northern league of reserves sides of Aberdeen, Dunde United, Dundee, St Johnstone , Inverness and top highland league sides and Tayport.
Plus a southern league of all the other SPL or first division sides with reserves teams from the south such as Celtic and Rangers reserves and Hearts and Hibs reserves. Real sides in the division would be auchinleck talbot, clydebank, Irvine, Gretna. Even get in Newcastle United reserves.
The real reserve only league do not work as they do not preapre teams for realk football, so how about creating a league with plenty of real first team sides in the leagues too.
