I think the AT-6 would be nicer, just because it has 30 30 cal machine guns for a little self defense.
The Wirraway did carry two .303's, in fact the Wirraway scored the RAAF's first aerial victory against Japanese forces in WWII.
I totally support this request, the Wirraway was to the RAAF what the Tiger Moth was to the RAF.
Yep, the 4th RAAF Squadron (Pilot Officer John S. Archer) did manage a victory against an A6M2 over New Guinea on November 1942 near Gona.
The Wirraway were the first "fighters" to engage japanese aircraft over Rabaul in early 1942.
It was used as observation, recon, artillery coop, straffer, etc... over New Guinea and Salomons until the arrival of the Boomerang. It was then relegated to the trainer role, the role it was concieved for at the beginning.
One of the modders was working on a T6 a while back. Don't know if any progress was made with it.
