Yipe something like the above is pretty reasonable.
Though I'd get rid of American Samoa, Tonga, Cook Island and Samoa very early on.
Similar to OFC age group qualifying currently, they can have their own little pre mini tourney. Then the winner of that tourney plays the next lowest FIFA ranked OFC team (currently PNG at 170th) over 2 legs (or at a neutral venue).
The winner of that playoff joins OFC WC qualifying proper.
Football Australia won't like the Socceroos having to play 6 low profile games H&A over 3 FIFA windows against say New Caledonia, Fiji & PNG but they may just have to wear it. They do currently play some AFC minnows in 1st stage AFC WC qualifying.
How the 4 yearly Asian Cup would fit into a AFC split who knows.
