Does anyone know how you could go about installing your own regulator at your house on your gas line?

Would it even be able to mitigate something like this?

Curious..

You would need a overpressure relief valve, not a regulator. And it's not clear to me what you would do with the overpressure except either (a) block it to protect internal systems, leaving the externals to fend for themselves, or (b) flare it off via a rooftop vent system, which would be quite hazardous and unwieldy to maintain.

but who doesn't want a flamethrower mounted to their roof?

You already have 'your own' regulator. And it will be as good or better than anything that you are likely to install yourself. Also, having two regulators in series will kill your flow, they need a delta to work with.
