Help with a simple build.

Hello, so I have always dreamed of building a home cockpit but I don't have the tech know-how or the money to do it. For now, I was thinking of at least improving my current setup, and need some help. At the moment I just have a basic Thrustmaster joystick which has a built-in throttle that sits on top of my desk. To start I want to get a separate throttle and stick. but was thinking if there was a way to make it so that the throttle and stick are sitting lower down it would make it feel more natural.

Is there something that I can attach to the desk that will allow the stick and throttle to sit lower down closer to how it feels in a real plane?

Thanks
