Courses and course formats

Hey guys,

I'm working on a project to redesign the appearance of the course.

I want to redesign the view of the course page but also the incourse like modules  (exemple /mod/page or /mod/quiz/ ).

I can do that with the template i need just to use the config.php

    'course' => array(

        'file' => 'course.php',

    ),

    'incourse' => array(

        'file' => 'incourse.php',

    ),

But with the template i can't share it with the community!

That is why i want to make a course format plugin.

My questions are the next.

1. How i can via the course format the appearance of the incourse (mods) redesign?
   
2. Can i load the incourse  with ajax without going to the the page of the mod?

in joomla they have a paramter that load only the content of the page.

index.php?option=com_content&view=article&id=1&tmpl=component

Greetings.
