IMO/IME, You would be better off going for a DC 45 final circuit and using something like a Triad C56-U as an input choke to get the B+ a bit higher.For the cap coupled final, you will need to drop more voltage off the rectifier somehow for lower B+ for the 45 plate, then decouple for the 26 driving stages.
I have done that before with a big power resistor and cap off the rectifier. Or with a power resistor in series with the primary HOT lead on the PT.
The major issue is the HV secondary of the PT in your circuit.
It is better suited for a DC 45 final.
Do you have another PT with a lower HV secondary voltage?

I have a feeling by the time I get both channels of this thing operational the B+ won't be too high anymore.
Right .
A second channel should drop the B+ a good bit.
