I suppose it would have some effect, but as the cathode current (as opposed to
the filament current) is so much less, I doubt it would make much difference.
Reversing the polarity of the filament supply periodically would seem the best
way to avoid metal migration problems: an artificial centre tap with a couple of
resistors across the filaement for the HV return would be best way to feed the
HV return, although they would need to fairly low resistance to avoid the
introduction of unwanted cathode bias.
