Honestly doubt the majority of German football fans would accept it, let alone embrace. Think it's just an idea, that will ultimately don't come to fruit like the one Rummenigge had regarding DFB-Pokal.
PS: For those, who didn't know or forgot- a few years ago Bayern requested a DFB-Pokal reform demanding the better Buli sides having byes in the first round and to be seated, so they couldn't face each other until the quarters. That proposal was voted down on DFB annual meeting, Expecting this proposition to suffer the same fate.
