Ki-45 would be nice, it would be nice easy target for P-38s but what real value does it bring? Or is it one of those "it's got a lot of cannons, we need it!" type of things?
i think it's the only cannon-armed japanese army plane for easrly and mid war
the front firing armament (ko and otsu) is comparable to that of, let's say, bf 109G and yak-9T
* Ko: 1 × 20 mm, 2 × 12.7 mm (.50 in), 2 × 7.92 mm (.312 in)
* Otsu: 1 × 37 mm (1.46 in), 2 × 12.7 mm (.50 in), 1 × 7.92 mm (.312 in)
* Hei: 1 × 37 mm (1.46 in), 1 × 20 mm, 1 × 7.92 mm (.312 in)
* Tei: 1 × 37 mm (1.46 in), 2 × 20 mm
* Bo: 1 × 40 mm (1.57 in)
