WCTFC dilemma

As you may or may not know, I'm trying to organize a world championship for the Half-Life Mod Team Fortress Classic.This is getting more and more difficult, because there are not many players left. The teams that are (almost) full are USA, Canada, Germany, UK, Poland, probably Finland and perhaps Spain. Now it's the question what to do.
The WCTFC was scheduled for January 2010, meaning all the teams would have to be ready by now, so the league schedule could be created and the participants could have started practicing for their first match.

I don't know what to do now. Possible choices are:

1. Play it as 8v8 cup with the available teams. (7 teams)
   
2. Play it as 4v4+ cup with the available teams. (12 teams)
   
3. Play it in a league system like NTFCL. (8v8, 7 teams)
   
4. Let the national teams play a few "friendlies".

Oh well, I will stop that there, I could only add crazy and impossible choices now.. ;)
I hope that someone comes up with a good solution soon, because the teams are there and willing to play.
