I'm confused by your question...can you clarify it a bit please? When you ask if it's possible to set up a Scheimpflug movement on a converging subject, the first thing that pops into my head is railroad tracks receding to the horizon. Setting up the movements here is pretty straight forward...front tilt until you get what you want in focus. But with the building, if the film plane and lens plane are parallel to the face of the building, the whole face of the building can be focused by extending the lens the appropriate amount...no other movements needed. You can use front rise to get more of the building into the picture, but no need for any other movements. Can you describe more fully what you're trying to do here please?
Thanks,
Dave
