The Baxandall class-D oscillator could do it, but it needs a pair 1.7kV
MOSFETs for the job. The Infineon SiC IMH170R450M1 would do it - though
it's a much higher current part (10A) than the job needs (about 1mA).
 
I've dived into the Infineon rabbit-hole which promises LTSpice models,
but wasn't able to find one.
 
Does anybody know of a similar - ideally cheaper and smaller - part for
which there is an LTSpice model?

It is an interesting problem, designing a logic supply that runs off a
1 KV DC supply. Even when the requirements are confused.

Actually, the uncertainty opens up more circuit possibilities to
consider. We can thank Sloman for being confused.
