Dump Super Rugby. New competition - 3 teams from Australia, 3 from NZ, 2 from Japan and 2 from China, 2 more - say 1 from SE Asia and 1 from Russia (Vladivostok). 12 teams, home and away, 22 match weekends + finals.
This would have Aus and NZ companies falling over each other to be sponsors - Dairy, agricultural and other products to be sold into Chinese markets. NZ would not be able to refuse the economics. The rivalry between Japan and China is immense, makes tribalism look like child's play. Russia would give 2 arms and a leg to belong to any high level competition. Of course these new Chinese/Japanese/Russian/Asian teams would use money to buy good players from elsewhere until they can mature their local product, just like the French and English currently do.
There should be enough money in such a competition to also subsidise a national rugby competition that's more professional and bigger then the NRC.
NZ have enough players that they could even keep there SANZAR teams and make 3 more easily if they wanted.
