Lots of warbirds out there with replica guns in place of the real ones. I know that "Lil Margaret" a 51 restored to stock has all the parts working including the gunsite and the wiring to the guns so in theory if they put active 50s in there, the guns would work.
There is nothing out there saying the gun ports have to be sealed up.
A more likely scenario would be someone using some of the warbird jets out there.
Think about a group of F86s or Mig 15s making a run. There are some Mig 21s owned privately, a couple of F104s, L39s, Hunters, Vampires etc all flying privately.
