I suspect some heresy here (could I be seeing heretics everywhere
tonight?), let me try you before we go further. Whether your
cathode is at ground potential or 20 kV below, or even 20MV below
for that matter, if it's surrounded by an anode 5V above its
potential then it will have exactly the same surface charge, do you
agree with this assertion?
Sure, but I haven't been talking about an electrolytic cathode
surrounded by an anode 5 V above its potential. I've been talking
about HV loaded cathodes, or electrolysis done like this:

A useful variation is to make the cell high voltage negative,
floating the electrolysis power supply, and making the anode "++" in
Figure 1 ground.
I've given the configuration the name "back side cell" in the rough
beginnings of a paper at
http://www.mtaonline.net/~hheffner/DeflationFusion.pdf
The fusion surface is the back HV side, or just under that back side.
