That's funny, I have almost this exact same shot, for the same reason!
As for GoPro mounts, they operate only on right angles. Look closely at the mounting gear and you will see it is all slotted, with some pieces that allow a 90 degree turn, but there is no free yaw. I guess they assume you will rotate the suction cup where you want it, which is probably fine outside cars, but in cockpits it can be limiting. That said, you do have to buy one mount or the other when you get the camera, so give it a go and see.
