Flightgear supports an https interface which you can use to have a browser display the existing instruments, but I don't know if the Rasberry Pi  has a built in  or comes with a web browser.

I'm thinking in terms of a FGFS instance with no scenery, no airport, just a single instrument, driven not from the FDM, but from input fed from the main FGFS instance over USB or UDP, perhaps running independently on a Raspberry Pi Zero.  Outputs for adjusting knobs back to the main fgfs via the same channel.
