Match times - Game day

Given there was quite a deal of discussion on a thread re the timing of the games on GF day I wonder what your thoughts are?
Currently with 4 grades we have 2 games at one ground with others at the opposition ground. Thus start times are 11:15 and 2:00pm roughly (2:15 if TV game) at each ground.
Night games are 4:55 and 7:40 with the 2 underage games normal times during the day.
If we go to the Under 18 competition as has been suggested often on this site then we'd see the times on GF and finals as the normal as you would not get one stand alone game either U18 or reserves at the opposition ground - costs for one game with staff etc just too much.
For example WWTFC v CDFC
9:15 U18, 12:15 Reserves, 3:15 League at Woodville rather than 11:15 Reserves and 2:00 League at Woodville with U18 at 11:00 or whenever at Elizabeth. Some ovals like Woodville could not do this in mid winter. May make upgrade at Thebarton worthwhile as currently Westies would be like Woodville as is Unley and Prospect and would need an alternative?
Would also impact on Night games - saturdays would be OK with say U18 at 1:00, Reserves at 4:00 and league at 7:00 but Friday night would possibly become a stand alone League game at say 7:15 with the U18 and Reserves the next day. For example WWTFC v Norwood Friday night at Norwood 7:15 then on saturday at Norwood 11:15 U18 2:00pm. Reserves rather than just one game the next day.
Would also mean less traffic on ovals as they would get a weekend off.
No lights and you'd have the GF/Finals times plus would need to fit in TV game at 2:15 somehow.
Just my ramblings but is something to consider re going to U18 or changing present structure especially as it gets harder to find volunteers to run teams with medical needs and trainers etc.
