I can't see the Prem teams agreeing to that if it doesn't apply to the other leagues for qualification too. The Pro14 could argue that they'll continue to leave out the SA teams from European qualification, but I doubt that the Top14 teams will agree to leaving out two of their teams too. At the moment they have 6 teams go into the Champions cup automatically (as well as the Challenge Cup winner if they're not already qualified), same as us, with the rest all going into the Challenge Cup draw. Can you imagine the fuss clubs would kick up if two of our top flight teams (in Domestic terms) get no European competition when teams like Zebre do?
