You could but it would be ridiculously slow. You could do it a few different ways, but the idea of the matter would be using a camera to render to texture or render to screen and then get the image, then apply the image to an image panel (optionally of a secondary window). This method would work and it would be easy to implement, but it would not be really viable for full-screen real-time applications (not on most computers anyways). I am not familiar with having multiple render pipelines within dbp, but I do know you can render multiple instances of dbp simultaneously, so I would imagine there is a way to do it.
