Making it happen will require compromise from both hemispheres but it's achievable and, of all the propositions, this is the one that has the most hope of success.
The IRB are clearly stalling, however, and frustration at their inability to decide will become painful for players and fans.
To highlight that, England will be forced to play the first of their three tests in New Zealand next year with a weakened team. The tyranny of the calendar has meant that once again the final of the English domestic club league will be played the weekend the national side is scheduled to leave for New Zealand. As a result, those players involved won't be available for the first test.
"It is frustrating," says All Black coach Steve Hansen. "More so, I think, for the players because we are asking them to do more and more and more and we are not giving them the opportunity to get rid of the niggles. If you can't get rid of those niggles in the off-season, then you will have them for the whole season.
"Players then end up playing at 80 per cent to 90 per cent of what they could be playing at. So to get an off-season of 12 to 16 weeks like they do in all the other contact sports would allow that to happen."
Hansen is not alone in his views. Every international coach agrees. Every test player agrees and yet there is resistance among administrators.
The NZRU had been hoping to see more enthusiasm for the shift when they attended a CEOs IRB meeting earlier last week. The appetite for change was lukewarm, which is why hope is only minimal that there will be any dramatic progress this week.
