The 129 B-3 is great fun, making the other variants wouldnt be hard as 90% of the model is right. It could also open up a new avenue of plane.
B-1: Forward machine guns and 6x50kg. Would be a good low BR bomber as it lacks the defensive capabilities of other planes like the 110 or Stukas. The real one could carry up to 300kg of bombs so it doesnt have to be 6x50kgs.
B-2: 30 mm MK 101 cannon with 100 rounds of ammunition. A HE autocannon much like the one of the Kugelblitz. Would be a solid anti-infantry / anti-tank. I wouldn’t even care if this was a premium vehicle, I’d buy that. Due to its poor perfomance and weak defence I don’t think it would be OP. A PTRS can blow one of them out of the sky easily.
And of course the Stuka Panzerknacker. It baffles me this has not already been added to the game.
This leads me to a question for the members of the community, do you think more variants of the existing vehicles should be added?
