Using a remote desktop or VNC client through PhoneCast VR (on GearVR) works, I don't know if this Samsung app will be available on Oculus Go, and I see no Remote desktop VR apps. You might be able to stream your desktop as a video stream and use a wireless mouse and keyboard.
I have not seen a way to surround yourself with different desktops in mobile VR. That would be my goal as well. It can be done with a highres Mixed Reality headset which I also have, but they need a Windows PC. That experience is adequate. I realized that I could just as well create my ultimate setup in real life, surround myself with 6 27 inch bezel to bezel Dell screens and stand in the middle.
