When the A-20G/Boston III get revamps to current standards, I would like to see the addition of the ordnance option to select rockets.
The A-20G was able to carry 12 4.5 inch rockets mounted under the wings using the T30 rocket launcher (same bazooka launcher for the P-38G/J rockets), giving the Havoc even more of a bang. These were not field modifications and were used often in combat missions. Below is a photo of an A-20G with the 8th Bombardment Squadron (Light) in New Guinea showing the front view of the bazooka launchers.
This is another A-20G from the 90th Attack Squadron in New Guinea, showing the rear view of the bazooka launchers
The Boston III were also able to use 4.5 inch rockets, but utilized a different launcher and were able to mount 4 rockets under each wing.
Closer view of the rockets.
And while I'm at it, I would also like to see an option for the A-20G to have the option of being able to select the quad 20mm nose cannon package. Over 200 were produced, and while the USAAF wasn't happy with it due to the cannon's unreliability, the cannon equipped A-20Gs were passed off to the Soviets that used them to great effect.
