Championship match

While reading the crosstable of the recent US Senior it appeared to be more of a regional event than a national event. Maybe it would be better to have, say, regional events, with the winners getting together to play for the championship?
After watching the US Tennis Open I began to wonder if it would not be a good thing to settle our National Championship(s) with a match?! Would it generate more interest?
