Is it possible to include multiple JavaScript libraries in an Ember.js add-on shim?

If I want to create an add-on for Ember.js, let's call it ember-awesome for the purpose of this question, that is a wrapper around a library awesome-lib.js and its extensions. How do I create a shim around that library and any extensions I want to bundle with it?

Assume for a moment that awesome-lib.js can have plugins or extensions to its funcitonality, e.g. awesome-ext-foo.js, awesome-ext-bar.js, etc. What is the best way to write a shim for and add-on that provides awesome-lib, awesome-ext-foo, and awesome-ext-bar to the component?

I thought I might be able to define a single shim, e.g. vendor/shims/awesome-lib-shim.js as such:

// ember-awesome/vendor/shims/awesome-lib-shim.js
define("awesome-lib", [
  "awesome-lib",
  "awesome-ext-foo",
  "awesome-ext-bar"], function(awesomeLib, extFoo, extBar) {
  return {
    "default": awesomeLib,
    "foo": extFoo,
    "bar": extBar
  };
})

And use it in my ember-awesome/index.js as such:

// ember-awesome/index.js
module.exports = {
  name: "ember-awesome",

  included: function(app) {
    ...
    this.app.import("vendor/shims/awesome-lib-shim.js", {
      type: "vendor",
      exports: {
        "awesome-lib": ["default"],
        "awesome-ext-foo": ["foo"],
        "awesome-ext-bar": ["bar"],
      }
    });
    ...
  }
  ...
};

This doesn't seem to work though. I can always create different shims, sure, but thought it would make the most sense to bundle like-components together in the same shim.

A good, real world, example of the type library and extension complexity I'm looking to write an add-on around is the markdown-it and its extensions
