Nikos Salas uses 12V zeners with the DN2540s in the CCS in his HPHV shunt regulator pretty much as your diode strings, but with the difference that each of the zeners is on the opposite end of the gate stop resistor from the gate of the MOSFET. It probably doesn't make any practical difference, but I would consider this better practice, as it isolates the gate from anything that could send RF noise to the active device.
As already noted, you don't need back-to-back zeners.
