I agree with MT on the possibility of injury to key personell, You could have a minimum selection quota of say 4 to 6 players that must come from the SANFL, WAFL, NSW/ACT/QLD AFL and the VFL. This would give fringe players a chance to impress on the big stage in a bit to try and make it to the AFL.
As far as the format goes, it may work the way the Americans do it. Have an Eastern Zone (Vics v Allies) and a Western Zone (WA v SA). Both games played on say a wednesday night and the winners of each zone play each other in the Final a fortnight later on a day to be determined. (maybe the weekend of the mid season break)
That way you only need to set aside two days in the whole season.
Well thats my 2 cents worth anyway. (Not that it's worth that.
