I do agree with you, this is a long shot and a tough one
I'm not too sure I'm understanding well your "elite rugby competition" point.
Or let me put this differently : How do you define the "Elite" specifics of Super Rugby ? What are the differences between our domestic championships and super rugby apart players number of matches, structural organization and maybe mentality ?
In my perspective, this elite rugby competition is the result of the organization and the goals of SH rugby at national and international level, all the organization of countries like NZ/Australia are made to feed the Super rugby and ultimately, the national team, this is what makes the super rugby an elite competition, the structure and the mentality behind this competition.
I do think that somehow clubs in France or England are trying to do the same (or would like to do the same), create an elite. Top14 or any other European domestics championship would like to see themselves as an elite competition.
However, they can't because they are too focus on themselves, not enough on the players (and the number of matches they are playing) or the national teams, too independent maybe (not being part of a larger and stronger european competition), too dependent on Financial results (or profits). I think you can change all this and integrate these clubs in a new organization if it is sustainable for them financially.
My point is to say : lets try to start slowly, lets create a super euro competition that would replace domestic championship, lets reduce match for players, lets see if it can be sustainable financially for clubs to be part of this competition and then I defo think that the elite thinggy could comme quite naturally if you create the environment for it. If the french clubs need to start to be competitive all along a year with Irish provinces, I think it will defo push them to be more "elitist" in their rugby and in their selection of players.
Again, I doubt that we can do without the clubs in France. Therefore, we have to start from the existing. Apart if somebody brings a huge amount of money to create franchise in France.
In that respect, the euro league idea of snoopy dogg seems to me quite reasonnable to start with.
