Can I setup a component constructor in controller?

components.my-bar.js

import Ember from 'ember';

export default Ember.Component.extend({
});

components.my-foo.js

import Ember from 'ember';

export default Ember.Component.extend({
});

controllers.application.js

import Ember from 'ember';

export default Ember.Controller.extend({
  appName: 'Ember Twiddle',
  author: 'quincy',
  
  initContext: Ember.on('init', function() {
    Ember.defineProperty(this, 'child', undefined,Ember.Component.extend({
      author: this.author
    }))
  })
});

templates.application.hbs

<h1>Welcome to {{appName}}</h1>
<br>
<br>
<div>
  <div> Case 1 </div>
  {{my-foo
    child=(component 'my-bar' author='quincy')
  }}
</div>

<br>
<br>

{{!--
<div>
  <div> Case 2 </div>
  {{my-foo
    child=child
  }}
</div>
--}}
<br>
<br>

templates.components.my-bar.hbs

Inside my-bar template. Author: {{author}}

templates.components.my-foo.hbs
