Why not have a Pacific Cup over Origin with Fiji, Sam, Tonga and NZ ?
Actually , I know why that wont ever happen, because our game is run by inward thinking morons.
The only way our game ever grows is through private investors like Perez or the guy that set up the Auckland nines.
Fiji do not have the Antipodean population to fill crowds and make it a spectacle. I believe Maori, Aboriginal, Tongan and Samoan populations in NZ and Aus do.
NZ involvement would ruin what could be a hard fought contest year in year out and ruin the spectacle by dominance. Alternatively, NZ may lose its Tongan and Samoan players making the 4 nations a cake walk for Straya - like the Anzac test is. Further - the Warriors would oppose it vigourously.
So I'm not keen on these 2 teams.
Tonga and Samoa with all test players from NZ and Aus or Maori and Aboriginal - with all test players from NZ and Aus.
These are good competitive teams that will get good crowd and fan support during Origin.
