New Hockey Trophy: World 9's Challenge

A few post back I talked about a new hockey trophy played over three formats of the game on one weekend.

Well in this post I am putting forward another idea for a new competition called the-

World 9's Challenge

We will take the 9's format that was used a few years ago in Australia as part of the International Super Series. The teams competing in this new competition would be all-star teams as per below-

1. Asian Hockey Federation All-stars
2. Pan America Hockey Federation All-stars
3. Oceania Hockey Federation All-stars
4. African Hockey Federation All-stars
5. European Hockey Federation All-stars
6. World All-stars

Now could this concept work? Where would it fit into the hockey schedule? Would the best players want to participate in it?
