Actually I was thinking in terms of full reverse V across each diode.

Just have to DC isolate each diode and provide the bias/reverse V separately for each one. No more complex that the shunt option bias system :-)

But shunt idea is a nice one too.

But only if each diode was to get the full reverse voltage. Dividing the
DC voltage between them may not decrease the coupling when the
capacitance goes as the inverse voltage squared. Half voltage, 4x the C,
twice the stray coupling.
