When I first read this, I thought it was an early April Fools joke. The format sounded so complicated: an 8-team tournament with the so-called hockey super-powers - Canada, the US, Russia, Sweden, Finland and Czech Republic; joined by a select team of North American players under 24 years old, and a select team of the rest of the world's players who aren't affiliated with the aforementioned countries.
Then I realized they were serious. What would be much simpler would be a select team of North American players against the rest of the world. That would be more like a Ryder Cup format.
Lots of obstacles to overcome here, including (as you mentioned) getting the pro clubs on board. It would make for some good hockey though...
If you help someone when they're in trouble, they'll ask you to help them when they're in trouble again.
