Constant-current sink: Yes, would be better. The circuit as drawn approximates to that, with the large -ve rail and resistor. But a chip of impure sand mineral, either NPN or JFET, would be a bit more elegant.
Yes. It's not a level playing field. Armoury of the sand/soot folk is more complete.
Attempts to cause heated cathode to emit holes into a vacuum is a logical absurdity... The only other solution, antimatter cathode emitting positrons is, I'm told, beset by either (a) expense of creating the necessary substances, or (b) the personal jeopardy in visiting anti-universe and returning with an anti-1j24b. And there's the practical difficulties that wiring a 1j24b and an anti-1j24b into the same circuit is likely to result in a flash, a bang, and the disappearance of both
