They should follow a similar format to the cricket, have a preliminary knockout round for the teams who are ranked low, once they have filtered out you add in everyone else.
Exactly what I was thinking. I understand the multi year long qualification process already accomplishes that but let that be used to decide top 24 teams and then another 24 teams after that. Make 8 groups of 3 and have the group winner advance to main draw of the WC to make it 32 team WC again. This way the additional teams also get to experience the overall WC event as part of a hose country.
