I don't think it is possible. I just emailed Hans some issues this morning, and this one was on the list. If I learn a different answer from him, I'll let you know (assuming Hans doesn't pop over here and tell you directly). My reason for wanting more than one module per project is almost exactly the same as your. I wonder if that points toward a solution. Maybe the plugin should associate IDEA modules with a "main" and "test" sourceset (with the "test" sourceset optional) instead of associating it with a project. That's how my own custom IDEA project generation is doing things these days.
