What Am I Missing?

Heater supplies. Thought is to use one heater supply. The AC portion would supply a single damper diode at 1A6/6V3. The DC portion, rectified and LDO regulated to ~6VDC, would supply a total of 1A4 load. A portion of that load, 0.66A would be near cathodes close to ground potential. The other portion of the heater load (0.73A) would be near cathodes at ~+150V. So the DC supply would be referenced to ~+70/75V.
Is this workable? That is to ask: must the damper diode supply be from a separate winding, or not? There is no cathode connection to the heater in a damper diode (6BY5GA).
I keep thinking that I'm missing something.....
