As the title says, give a project that you wish had been completed, just for use in Aces High. These may have been canceled due to issues with engines/ armament, Production, Political or just the need disappeared.
CAC Woomera
http://en.wikipedia.org/wiki/CAC_WoomeraThis aircraft started testing in September 1941. The first prototype exploded in mid-air (most likely due to the fuel tank design). The redesign and 2nd prototype did not fly until June 1944. *By the time production was due to commence, the dive-bombing concept had fallen into disrepute, the RAAF was filling the light bomber/reconnaissance/strike role with British-designed Bristol Beaufighters (which were being made in Australia by the Department of Aircraft Production); US-made B-24 Liberator heavy bombers had also become available. Consequently, the original Woomera order was reduced from 105 to 20. After the first CA11 flew, the whole program was cancelled and the production capacity set aside for Woomeras at CAC was switched to P-51 Mustang fighters.

I think this would have been a fun plane to fly in AH. The speed was a little slow, but it carries a good sized bomb load for 1942-3 (the year it might have gone into full production) Also the forward armament was quite strong. The defensive armament could do with a little work, but it looks like the Barbettes would provide a good coverage (and who knows, CAC might have upgraded them to 20mms as the war went on).
