Well Italian vehicles in game are actually simply not unique enough so I suggest major rework on the existing Italian vehicles first the Fake C 202 EC plane:
The C 202 EC is some weird ground attacker prototype that had MGs on the wings probably since it was never used in combat better replace it with C 202 CB BR I fighter plane that has 2x100 kg bombs it will be very similar to the Soviet Yak. Keep in mind the stats will also be better since it no longer be this weird ground attacker since what you see on C 202 EC is a ground attacker not a fighter plane so better give us a real fighter with bombs that is the C. 202 CB.
Then Replace the Re.2000 serie 1 with with re.2002 early 2 Γ 50 kg GP 50 bomb
250 kg GP 250 bomb and move it to BR II:

And finally the best option for BR II Italian tank is the existing 75/32 M41 all it needs is HEAT shells and can be moved to BR II:
As you can see this turtle is far better armored against planes then even BR IV and BR V German tanks and the HEAT ammo will give it nice anti tank capabilities that can deal with the Sherman and do damage to infantry to be honest will be one of the best BR II tanks Axis faction has. And for BR I they can put on its place the 75/34 M42 that has less armor on top and no HEAT ammo. But this turtle is absolutely armored against 20mm cannons and against all Soviet and Allies rockets at lower BRs cant pen the roof. So yes its a missed potential if this tank has no HEAT ammo.
This small changes will make Italy far more enjoyable with the equipment we have in game.
