Halon extinguishers are just filled with Halon. Halon is an oxygen displacer, similar to what CO2 does.How does a Halon extinguisher work? Can you repressurize with air or nitrogen?
The problem is Halon was/is highly damaging to the ozone layer, much like original freon.
You could fill it with whatever you want as long as you don't exceed the limits of the container.
Nitrogen would be fun but the cylinder would get extremely cold, extremely fast and possibly compromise the integrity of the vessel, if the vessel held in the first place. Halon is a liquid at around 70PSI. Nitrogen, MUCH higher
