As you are already going to use vacuum variables you can put the choke after
the roller inductor to the 50 ohm side.
The anode variable and roller must withstand twice your anode voltage and
the blocking capacitor needs much more capacity.
But then your choke can be become much smaller, 50-90µH are sufficient and
that can be wound without any in band resonance.

I have not settled on the oputput network yet either.  I have a large roller
inductor and two vacuum variables for the ouput (tank) network and I am
quite aware of the plate choke issue.  At least one person has reported
using relay switched plate chokes to make sure they can use their amps on
all the bands.
