I think it's an great idea, but given the current state of the project, I think you would need to redo a lot of mechanics (movement, shooting, climbing, enemies, animations etc) to adapt to VR, and the project is not easily set up to be used in VR. You would also need to adapt the UI elements to better fit in VR. I think it would be more productive to start a project from scratch and use the PerroAutonomo 3d models for the scenarios or maybe fork the project and use the current scenarios for a starting point.
