IMO, flashing independant radios isn't a good idea. When I flashed a rooted stock rom when the update was released, it flashed the latest radios with it. So when I jumped back on to myns rom, all has been golden. I suggest trying to flash a rooted stock rom with the radios then flashing a custom rom.
