I said electrostatic focus - not deflection.

Sure, you can use a 12LP4 if you:

* Modify the filament voltage from 2.5 to 6.3
* Swap out the HV connector
* Hack up the metal funnel to handle the shorter CRT
* Possibly swap out the yoke because of the steeper deflection angle
* Somehow add magnetic focus and disable the high voltage focus supply
