Surely it's not that hard.
Run a 6 team Super AU where the top 2 qualify for SuperRugby, bottom 4 in "insert sponsor here Cup" for the following season.

Japanese rugby have top 2 qualify for SuperRugby, next 2 in "insert sponsor here Cup" for the following season.
Play 3 weeks of local rugby then 1 week international.
NZ teams get to have their softer matches & Aus & Japan get to play the tough NZ teams.
The issue you have with a set up like that is scheduling, you are okay with the first part of the season domestic, but the second half "sponsors cup" needs to be scheduled over three countries with what one or two weeks notice, I don't think that is practical for a variety of reasons.
Okay just saw the following season, but that does bring up the issue of form each year.
