How to combine (minify) compiled Angular 2 components?

trying to minify compiled source code of a project for production, I'm using Gulp as the task runner.

the source files look like this,

html

<!--... . .  various scripts and styles . . . . . --->
<script src="node_modules/angular2/bundles/angular2.dev.js"></script>
<script src="node_modules/angular2/bundles/router.dev.js"></script>
<script src="node_modules/angular2/bundles/http.dev.js"></script>

<script>
  System.config({
    packages: {        
      app: {
        format: 'register',
        defaultExtension: 'js'
      }
    }
  });
  System.import('app/main')
        .then(null, console.error.bind(console));
</script>
</head>
<body>
  <app></app>
</body>

my app directory structure is as follows,

.
├── main.js
├── main.js.map
├── main.ts
├── main.app.js
├── main.app.js.map
├── main.app.ts
├── x.component1
│   ├── x.component.one.js
│   ├── x.component.one.js.map
│   └── x.component.one.ts
└── x.component2
    ├── x.component.two.js
    ├── x.component.two.js.map
    └── x.component.two.ts

app/main.ts

import {bootstrap}    from 'angular2/platform/browser';
import {MyAwesomeApp} from './main.app'

bootstrap(MyAwesomeApp);

main.app.ts

@Component({
    selector: 'app',
    template: `
        <component-1></component-1>

        <component-2></component-2>
    `,
    directives: [Component1, Component2]
})


export class MyAwesomeApp {

}

then the components,

@Component({
    selector: 'component-1',
    template: `
        Lorem ipsum dolor sit amet, consectetur adipisicing elit. Beatae ducimus, saepe fugit illum fuga praesentium rem, similique deserunt tenetur laudantium et labore cupiditate veniam qui impedit, earum commodi quasi sequi.
    `
})


export class Component1 {

}

and

@Component({
    selector: 'component-2',
    template: `
        Lorem ipsum dolor sit amet, consectetur adipisicing elit. Beatae ducimus, saepe fugit illum fuga praesentium rem, similique deserunt tenetur laudantium et labore cupiditate veniam qui impedit, earum commodi quasi sequi.
    `
})


export class Component2 {

}

All the TypeScript files are compiled down to ES5 JavaScript, further need to minified to main.js

so my questions are,

1. Can I run a task to collect all the compiled .js files to minify to a single file and reference it as main in production branch?
2. Does this breaks the module system import {x} from 'y'?
3. If it breaks the module loading system, what can be done to concatenate files on an Angular 2 application?

my TypeScript version is, 1.8.2

Thank you for any help.
