"How do you regulate the g2 B+ at a fraction of the anode B+?"
Use a Maida style regulator. I suggest you buy Tom's PCB, in its fully populated version. Pay the man his money and leave SMDs to an expert.
Tom's PCB is highly competent. You might have enough current for the screen grids and the small signal circuitry. ;>)
