Love to see it. More rising to competitive levels the better. Get the 2nd tournament going with 4 sides below the 6 nations and bring in relegation. Georgia are about to go past Wales in the ranking for what they're worth...
I don't think any of the 6 nations unions will ever allow promotion/relegation, the cost of relegation would be too high. Maybe if it changed to 4 teams per division (home and away within your division each year), so that the 2nd division was still strong and commercially valuable. But I think expansion would be more likely.
Another option would be to hold a rugby euros cup style tournament every 4 years (between world cups). Could easily do that with 12 teams now.
