Will, no. What you describe applies to a Pi-net, not a Pi-L. BTW, do you
have a call sign?

"Simple,
Determine the voltage across the 50 ohm load from the power in watts.
Then use a load capacitor with a voltage rating equal to or up to two
times the load voltage. The tune control is two times the plate voltage
and so is the coupling capacitor."
For the Pi-L, just take the intermediate impedance used in the Pi-L
design (often 300 ohms) instead of 50 ohms. You need to use the actual
PEP power as it would be measured by a peak-reading wattmeter, of
course, plus a safety factor.
