I was telling Ross I already knew what your answer would be. Except that means handling both rfkill switches from the kernel, ignore the soft killswitches that'll only change the powered state of adapters, and then poke bluetoothd directly about those. That means gnome-bluetooth handling 2 types of killswitches. Which is the type of problems that having a decent kernel rfkill subsystem is trying to avoid. I'll also note that setting the Powered state on the adapter on the bluetoothd side won't be updating the rfkill state to soft killed. So there's a few holes in your theory there.
