I'd go for 2 leagues of 16 bottom 2 relegated, 3rd bottom top league play off with 3rd top of league below. Start the season in August and play on Saturdays (Ross Co away again on Christmas eve anyone?). Bottom league of 10 top 2 promoted bottom two in play offs with winners of Highland & Lowland leagues. No chance of clubs in Premiership giving up 4 home games especially if they include the ugly sisters & the TV money they bring,or of the broadcasters giving up the ugly sister's 4 league games
