Is there a way to create a custom model/view for an existing component? For instance, if you wanted to change the Query used in com_content to include data from other tables when looking at a Category, is it possible to create a new modal/view to make this happen? Or if one wanted to integrate other types of content (like using the twitter api or tumblr api) to put contentment in the category flow (and maintain the correct pagination) it would require change the model, but can a custom modal be created without hacking the Joomla core?
thanks!
