I’m not sure if you can setup two controllers for the same axis in X-Plane natively and have it play nice, but try checking out UCR. I believe it lets you add multiple axis together, which paired with VJoy to bind it in X-Plane may work. I used this setup to combine racing pedals with two separate axis for left and right yaw into one axis that I bound in the flight sim. Source: about 2 years ago
