I doubt one of the Istari or an elf-lord could kill the Nazgul but they might make them lose their shape and power to influence the physical world as happened at the ford of Bruinen.
I think in Rivendell Gandalf told Frodo that only the elves who had been in the blessed realm had power over the Nazgul. Since the Istari were Maia this makes sense.Maybe it is because Glorfindel and Gandalf had both seen the light of the trees that the Nazgul fear them.
