An experiment that might interest you and clear up some of this discussion. In 2007 a paper was published from Sandia used deuterium fuel gas in the Z-machine. The fuel gas was stored at the cathode potential (-4 MV, much closer to the peak in D-D fusion cross section than 100 keV.). This is common practice in Z-pinch machines. No increase in radiation yield is observed as your hypothesis suggests. Similar experiments are conducted on plasma focus devices without any significant increase in radiation yield. You can argue that the pinch devices are fast pulse machines and the fusor is a DC device, but the time to bring the fuel gas to the local potential is a fraction of a nanosecond while the pulse duration is >100 ns.

I wish you luck in your experiment but based upon the existing data you will not see an increase in fusion yield over storing the fuel at anode potential or some other potential.
