I don't want NZ to leave OFC.
I would like either of -
1. Top qualifier from OFC qualifying, which will be the AWs basically eternally, join last round of AFC qualifying. However is zero motivation for AFC to allow that to happen - unless OFC's 1 spot at World Cups was now thrown into the AFC mix. However then why would the OFC Confed want to lose their guaranteed spot.
2. My preferred idea, of a combined East AFC/OFC Nations League running somewhere in the first 1-2 years of a WC cycle. AWs in Division 1 with Aussie, Japan & Sth Korea. 6 games H/A, with a final. Relegation straight to Division 2 for the bottom team.
So just 4 FIFA windows required. 3 for the 6 H/A games and 1 for the Final.
Would give AWs 3 actual competitive home games (Socceroos, Blue Samurai & Koreans). Then if AWs are down in Division 2 it's likes of China, Thailand, Vietnam, Nth Korea - and the buzz of trying to get promoted to Div 1. ie actually winning something worthwhile. And the other OFC teams the same down the Divions playing East Asian minnow nations, pro/rel as well
A bit tricky as in the first 1-2 years of a WC cycle is Asian Cup qualifying for AFC teams plus the Asian Cup itself. But again I'm only proposing 4 windows of games. The first year of a WC cycle, the FA like to try source big name friendlies for the Socceroos - like Ecuador x2, Argentina, Mexico & England played Aussie last year. But that could get harder to organise as UEFA & CONMEBOL are looking to setup a combined Nations League playing all games in Europe from memory, ie teams outside those 2 Confeds will need to look elsewhere for matches
