This is what some of us are hoping. The idea has been suggested here quite clearly. My contention is the amount of common mode current found on the coaxial feed to a properly designed and tuned ground plane is so small pyhsical isolation and a balun will not improve performance by any useful amount.
Same for coaxial sleeve decoupling. Some of those are not designed very well though so there is room for improvement.
