That's a clever idea. I'll have to give it a try sometime.

My nixie watch has zero anode resistors. I added a current sense circuit to the
HV supply feedback circuit. I only light one tube at a time, using a total of
16 cathode drivers in TD62083 parts. It works fine. See my website-google nixie
watch theory to find the page.

It seems to me that would only work if you only selected a cathode for one tube
at a time. Otherwise (if you tried to light both tubes at once), only one tube
would light, pulling the
anode end of the resistor down to the maintaining voltage, which would be
insufficient
to light the second tube (because it is now below the striking voltage).
