Multisite or Not

I am implementing a website with a structure like coursera…

I want to create a custom post type with the following features

Custom Taxonomy A
Custom Taxonomy B
Custom Taxonomy C

Custom Taxonomy C -> Sub Category -> Parent Post -> Child Posts

Each of the parent posts under “Custom Taxonomy C -> Sub Category” will have common sub pages which makes it look like a full website on its own with similar menu structures made from the subpages.

Eg. Like that of coursera, each of the posts will have home, the author, text book, syllabus, etc.

I was wondering how to implement this. Currently my plan is to create the parent post which will have custom meta boxes with fields to select which of the sub page corresponds to the about, syllabus, text book, etc, so they could a custom menu name could be chosen for them instead using their own title that comes with wp_list_pages();

I am not sure if i am on the right track
