It's not only baroque, it is definitely not a reasonable way to implement this. The Stroke dialog must not alter the image structure. Simply because there is no guarantee that the user (or some plug-in) doesn't do anything else with the image while the dialog is opened. I don't see though why it requires massive changes to implement a preview of paint strokes. It should be possible to do this after some refactoring of the code.
