There have been a number of articles over the years about setting up layouts with restricted views - for example, the only view you have of a scene is thru a fence or a building window. Between that and clever use of scenic blocks, it should be possible to do what you want.
I don't have any specific article info, however, but I'm pretty sure this was discussed in reference to John Allen's modeling at some point - he was a photographer so would have probably employed these tricks.
