Not sure if this is quite on the same track, but I'm planning to make a plugin which will allow JEQL to operate within JUMP. JEQL provides a much higher-level language than Beanshell, so it might be close to what you're looking for with a "Model Builder".
Ultimately it would be cool to provide a Visual Programming interface to JEQL, which would make this even easier to use. Does the Sextante Model Builder provide a graphical interface?
