In theory I've got an idea on how to create a virtual set that could be used during live streams of a show using +Open Broadcaster
studio and a video chat program as well as a something like gimp to create the virtual set. This way you and hosts or guests can appear as of you are in the same place.
Create a set using your favorite image manipulation software.
Now clone the desk to a new layer with transparencies around the rest.
In OBS studio import both images into a new scene with the full background as the lowest layer and the desk by itself above that.
Both guests and hosts need green screens for the next part.
Using chroma key insert both people to appear on the show in the same scene as the desk by put there feeds between the full background and the desk only image.
This should work but I haven't tested it. If you try it please let me know how it goes+DoorToDoorGeek
I think this could be a interesting way for you to step up the production value of your shows
