If you want to stick with that way-over-complex design you could look into versapac 6 windings coupled inductors.

Thanks piglet I will.

Perhaps I should have mentioned that it's not for volume production and I already have suitable parts except a transformer.
Having to buy chips would cost more and there's no education in wondering what's inside a chip.

I would not even try that circuit. Better to redesign to use either a single inductor or a dual coupled inductor like DRQ127
series. if necessary follow with a cockcroft-walton multiplying rectifier.

I'm sure there are plenty of ways to turn 12V into 200V.
