Streamline Japanese procurement

[mexchiwa]

If you could streamline Japanese aircraft, engine, and armament procurement, so there would be less duplication between Army and Navy, how would you do it?

A5M or Ki-27?
Ki-44 or J2M?
Ki-21 or G3M?
Ki-49 or G4M?

Or were these aircraft sufficiently different to all be needed?

What about engine production?

(sorry if this sounds like an essay question, just trying to start a little chat)

The J2M was too late, so I'd go with Ki-44 all the way. The Ki-27 needs navalization, so go with the A5M instead also for the Army needs?
As for the bombers - go with the ones where self-sealing tanks can be installed more easily?
