I have said it for years .... here are some of the things I would like to see .....
3 leagues of 16 .... which means 6 more ambitious new teams can come in - ICT, County, Gretna, Peterhead, and even Elgin havent done that badly when compared to some of the perpetual table proppers in the 3rd !!
Play each other once at home and away meaning 30 games and to offset the 'lost' 3 (or possibly 4 in SPL) home games initiate a divisional cup ... a bit like the Challenge cup but for the repective divisions only ....
Guaranteed 2 up, 2 down each season. If a team does not have a 6000 all seated stadium (for SPL) then they can use the seated part they do have until they build it. Give them a grace period of 1 season where they can use the increased revenues from the higher league to help them meet the required standard.
If the SPL arent prepared to give teams a full season to get stadia up to SPL standard, then get rid of March 31st deadline - teams in lower leagues usually dont know if they will get promoted in March and spending money 'speculatively' could kill a lower league club if they dont win the title after taking the financial gamble. By all means give a team till 31st March to apply for the SPL, but give them until start of season to have the ground ready ! If Tullochs can build 2 stands in 43 days, then any team in that spot can surely give David Sutherland a ring to have their stadium ready for the new season !!!
Get rid of the USH requirement - the costs are too high and it ruins the pitch as we know. Making St Mirren install it for maybe 1 season is also ludicrous. Change the rules to read 'adequate pitch protection' which would allow for 'blankets', air domes etc. If a club has more than 'x' number of games called off when other teams are ok, then they could be fined ..... we all know how few games ICT had called off before we installed the USH and County's problem doesnt seem to be snow or cold weather but 'drainage' and USH only makes that worse !!!
Enable a system to allow ambitious teams from 'non-league' roots to get into the senior setup - including HFL, South/East Scotland leagues and Juniors ... (not sure how that would work, but like the idea !!)
