Wings Inspired by Blast Doors
I know wings gets brought up a lot, but I've a different kind of solution.
Wing blocks, that look like blast door blacks. The trailing edge being the little rounded bit and the rest being the block that doesn't attach on two opposite sides. They make slick, nice looking shapes because of their lovely texture, and if they could simply stabilize vertically like a thruster that points up and down, more powerfully overriding as you flew faster in thicker atmo, then you could effectively make a 'simple' wing behavior. The effect could be scalable where the more blocks you have on your craft, it's effectively like more thrusters at work.
Let me know if this sounds like a more fun idea than slapping some premade models on your craft and calling it a day.
