There are such mods for the missions! I don’t remember the names but I think I will find them again.
As for the Wings: IMO stock aerodynamics and heating are still not good enough, I still mod them.
I don’t know if wing shape matters much.
In FAR they do. I once even built a plane with a sweeping mechanic (using a hinge from infernal robotics). It was a challenge, but fun. In the end it resembled a MiG-23 a bit.
The cool thing about FAR is: designs that work well in real life work in the game too, for the same reasons even!
