I think you would need a mechanical breaking gap like a rotary gap to
properly quench a DC supply.

No, you want to hit the primary with an impulse, at let the natural
resonance of the tank ring it up to a high voltage. A few hundred breaks
per second gives the secondary a chance to ring nautrally in response.
You don't want to overdrive the coil or excite higher harmonics.

Not by any means I am aware of, nor would it help us any.

Yes, it's that simple, but not something you need or want to do. 60Hz is
quite practical to work with.
