If you really want a WWII era (well, Korean War) Close Air Support aircraft, get a Spad!

Douglas A-1 Skyraider

"Armament
Guns: 4 × 20 mm (0.79 in) M2 cannon
Other: Up to 8,000 lb (3,600 kg) of ordnance on 15 external hardpoints including bombs, torpedoes, mine dispensers, unguided rockets, and gun pods."

Powerplant: 1 × Wright R-3350-26WA radial engine, 2,700 hp (2,000 kW)

This would need to be replaced by something like the PW100TS, big brother of the venerable PT-6.

Looks like a P-51 canopy on that magnificent bastard of a plane.
