Yes, when you have tested I would be interested in seeing it and you may want to consider contributing it to the project.
I managed to find a good description of this pattern, including some sample Java code from a reprinted Java Report article (July '98) on the web (searched for "Event Notifier Pattern" on Yahoo!). A web event model is something I have been very interested in using for some time. Barracuda (barracuda.enhdyra.org) implements a similar pattern but it seems web-centric (ie. dealing with HTTP events) and I am reluctant to try to integrate it with turbine. To my knowledge, an appropriate one-to-many event handling model is lacking in most web app frameworks. J2EE Blueprints describes a simple approach similar to Turbine's "Action Events." Events are mapped at the web tier to "business events," which are handled by a series of case-switch statements in a stateless session bean. A true object-oriented event notifier implementation would be an improvement over this procedural approach. In the meantime, I'll use yours and Daniel's advice on implementing services.
