Multiple Git submodules sharing same folder?

I'm about to ship some libraries, and want to produce something like the following:

Project
  Assets
    Plugins
    Scripts
    AwesomeLibraries
      One
      Two
      Three
      Four
      Five
      Six

And version the libraries only (for sake of example), like this:

Main repository to maintain submodules (checked out into 'Project/Assets')

/

Submodule 1 (checked out into 'Project/Assets'):

AwesomeLibraries
  One
  Two
  Three

Submodule 2 (checked out into 'Project/Assets'):

AwesomeLibraries
  Four
  Five

Submodule 3 (checked out into 'Project/Assets'):

AwesomeLibraries
  Six

You may ask why: Submodule 1 contains the open sourced libraries, users should check out into their Project/Assets folder. Further submodules contains the closed sourced / monetizing libraries, while users should also check out into Project/Assets folder, like the rest of the libraries, while everything should be lined up in a Project/Assets/AwesomeLibraries folder (kind of "amutomatically").
