Does anyone know why, in 1942, Lawrence Wackett / CAC did not just upgrade the Wirraway airframe to a single seater with P&W R-1830 engine rather than going through the substantial redesign and new jigs/parts required to produce the CAC Boomerang? I know the Boomerang used a lot of Wirraway parts, but would it not have been far quicker just to upengine the Wirraway with the P&W Twin Wasp (+445lbs weight), delete the second seat (-100lbs?), reprofile the canopy/rear fusalage, and add more armament. The result would probably have been lighter than the Boomerang ((5375lbs empty vs the Wirraway's 3992 lbs) and would have looked a lot like the FW190 (on which data was available at the time from UK sources).
