Re-read my post. Most of the minnows already prefer a one off home-away playoff scenario. These are the teams with a disproportionate share of the voting power. They wouldn't care about this type of multi-stage proposal. The only real minnows who would are the teams like a San Marino who are gifted group matches UEFA is the one confed that does this. I don't even think that if UEFA went to smaller groups with a two-stage approach that a country like Wales would care, because they would likely get more matches (bit still not qualify for the WC). They would get these matches when they would otherwise be off.
