I'm not aware of any packages for doing such plots. Conceptually, presumably a ROC curve for a 2d classifier would be a 3d chart, with x-axis being FPR for 1st classifier, z-axis being FPR for 2nd classifier and y-axis being TPR. You would get a "ROC surface" rather than a ROC curve. Does that make sense?
