I know it's not been discussed much on here but the SFA have been working with the non-League clubs to try to set up a 'sort of' pyramid.
The HL clubs have all got their licences arranged and there's moves towards a 'Lowland League' with the best from the EOSL and the SOSL plus any juniors who want to get involved. Clubs who don't meet the licensing criteria won't get in.
Being involved with Whitehill I've seen most of the paperwork (including an SFA questionnaire) and the way things are going, clubs are wanting a system where the leagues below the current div 1 are regionalised. Also many clubs, if they commit to the HL/LL, would like the option of staying there even if they win it, as they simply can't afford to be in a league with midweek games away at, for example, Stranraer.
