I'm not very fond of replacing the model object, but I guess sometimes it is the only or the better choice. I do not know your application, but I guess I would go for a single model which contains all form component, whether set visible or not. And on submit propagate the information into proper businsess object if applicable. But of course that is only a suggestion and there are possible more approaches to it.
