Can we make a better wp user frontend plugin that can handle post types, custom fields etc.

Hi! Guys is it possible if we can make a more complex version of wp user frontend plugin. It allows your user to add and edit post from the frontend. It would be a nice feature for the prosites plugin. Not all would want their users to access the wordpress admin. So if this is possible maybe we can extend its features and allow post types, custom fields, and a panel creator would also be helpful.
