For my 2c, if you look at the Asian Federation it is currently split into 5 federations
- WAFF-West Asian Football Federation (12 members)
- CAFA-Central Asian Football Association (6 members)
- SAFF-South Asian Football Federation (7 members)
- EAFF-East Asian Football Federation (10 members)
- AFF-ASEAN Football Federation (12 members)
Throw in Oceania (11 members)
I say combine them together and split down the middle. So you have
- Asia-India = WAFF+CAFA+SAFF = 25 members
- Asia-Pacific = EAFF+AFF+Oceania = 33 members
Move Australia back into Oceania so we get to play each other more often
Time zone spread across the two confederations is minimised.
Split any FIFA tournament allocation places down the middle, if there's an odd number, have a Asia-India v Asia-Pacific playoff for the last spot. So Asia-India, and Asia-Pacific would have 2.5 places World Cup places each
FIFA Club = 1 place each i.e. winner of Asia-India Champions League and winner of Asia-Pacific Champions League
FIFA Confederations Cup = 1 place each i.e. winner of Asia-India Cup and winner of Asia-Pacific Cup
Asia-India and Asia-Pacific cup every 4 years, and each sub-confederation would have their own tournament every 4 years as well. So the 4 year cycle is ...
- Year 1 Sub-Confederation Cups - Oceania Cup, AFF Cup, EAFF Cup, WAFF Cup, SAFA Cup, CAFF Cup (these act as qualifiers for next years 16 team Confederations Cups so first 5 to qualify)
- Year 2 Confederation Cups - Asia-Pacific Cup, Asia-India Cup (winners to next years FIFA Confed Cup) + start of World Cup Qualifying inside sub-confederation
- Year 3 World Cup Qualifying - Final phase involving qualifiers from each sub-confederation.
- Year 4 World Cup + qualifying if necessary for next years sub-confederation cups.
For Asia-Pacific, have a condition in the constitution that any final tournament has a minimum number of (ideally 3) from each sub confederation.
So for...
- 8 team tournament - Host+EAFF(2)+AFF(2)+Oceania(2)+Playoff for last spot
- 10 team tournament - Host+EAFF(3)+AFF(3)+Oceania(3)
- 12 team tournament - Host+EAFF(3)+AFF(3)+Oceania(3)+2xPlayoff for last spot2
- 16 team tournament - Host+EAFF(5)+AFF(5)+Oceania(5)
... ideally 3 from each sub-confederation as then it won't just be NZ,Australia always qualifying from Oceania, but Fiji, Solomon Islands, Tahiti etc will think they have a legitimate shot as well for the last spot.
For age groups, every 2 years there would be a sub-confederation tournament that then feeds into a confederation tournament later in the year that qualifies for the FIFA tournament.
At a club level, probably be a 16 team Asia-Pacific Champions League, something like A League winner + Phoenix qualify direct for Asia-Pacific champions league. A league runner-up, FFA cup, ASB Premiership winner etc qualify for qualifying phase with Island champion etc. Non-qualifiers drop down into a 16 team Sub-Confederation Champions League running underneath.
Yes, we will have less chance of qualifying for the final FIFA tournaments, but if we do get there we will have played in a tournament with Australia, Japan, South Korea, China etc and so will be worthy of our spot. For national teams mens and womans, we will get a 4 year cycle of meaningful games. For age group, 2 decent tournaments every 2 years. Our clubs will have a meaningful champions league to aspire to each year.
