Ahh...gotcha, but the A-26 Invader would have made a good dedicated Night fighter had it made it into the war sooner.
It was used on night interdiction missions in Europe from late summer 1944 onwards, with the 9th AF.
It depends on what altitude you want to "play" at.
the engines in an A-26, while good for 2000hp at take off and and Military power at 1500ft were rated at 1600hp at 13,500ft military power.
The engines in the P-61A&B were rated for the same 2000hp at take off but their 2 stage inter-cooled engines allowed 1800hp at 15,500ft and 1650hp at 22,500ft. military power.
While you might have been able to stuff the bigger superchargers, intercoolers, scoops and ducting into the A-26 if the P-61 airframe had turned out to be a turkey there doesn't seem to be much point if the P-61 exists.
