Burning natural gas to make electricity to run a heat pump isn’t elegant- but it is more efficient.

We need a heat pump that is heat-powered…

There are old propane refrigerators which do exactly that (heat powered heat pumps).

Have you done the math to check whether it's more efficient?

A natural gas furnace is up to 98% efficient. A natural gas turbine is 40-60% efficient; a modern heat pump can have a COP of 3 or even 4, for 150-200% equivalent efficiency (ballpark).
