Now, now, no bickering.
One thing I'd love for the G.55 is the Serie 0 option.
The first planes had a hub 20mm gun, but 4x 12.7mm Breda SAFAT MGs, two on top of the nose and two below the nose, all synchronized.
Later models removed these lower 2 guns, due to difficulties in accessing them for servicing and reloading. Probably for lack of firepower, too. They put the cannons in the wings.
Serie 0:
4x 12.7mm
1x 20mm
Serie 1:
2x 12.7mm
3x 20mm
It would be a nice option like the 7mm wing guns on our C.202 and C.205, not the most powerful, but interesting for variety.
