Creating a menu structure based on Content Types Alias
I have never seen a module that does that, but you could try Import HTML. More details from the module's project page:

Import an old existing, static HTML site structure into the Drupal CMS as structured nodes!
Allows an admin to define a source directory of an existing traditional static HTML website, and import (as much as possible) the content and structure into a drupal site.
Source files will be stripped of exisiting chrome and navigation elements before being inserted as nodes.

As alternative, I would use the https://www.drupal.org/project/menu_editor module to quickly build out the menu structure of the already imported content.
