Setting up a virtual XR stage inside Unreal and be able to view other Unreal contents projected on virtual XR stage

I want to create a virtual XR stage set inside Unreal Engine to show our client who are unable to come to the physical XR stage set. We have about 15 different massive landscapes created in Unreal that needs to be displayed on the virtual XR stage screens and be able to adjust the landscapes while you are in the virtual XR stage in Unreal.

  1. Is this possible ?
  2. What is the best way to do this in Uneal ?

PS
I was only able to do this by creating a virtual XR set and bring it into one of the landscape project and offset the XR stage set far below ground level and link one of the landscape’s camera to XR stage screen using render texture. This allows me to edit & navigate from both XR set and landscape freely at the same time. However, it is impossible to bring all 15 landscapes into a single project.
