Another option could be to combine the AFC & OFC and push for 10 spots.
Divide the combined federation into 3 conferences:
West Asia (4 spots) - All of the Middle East countries as well as Afghanistan & Pakistan
Central Asia (4 spots) - The rest of the “stans”, China, India, Korea & Japan
SE Asia & The Pacific (2 Spots) - Every country from Myanmar east to Kiribati.
