Meteor 1.3 - lazy loading or evaluation of files - meteor

Question

I am very excited with ES2015 modules in Meteor 1.3. We have written an app with medium complexity with Meteor 1.2. As we have very large number of templates and files, it is taking a bit of time to download the content on client side. so I am interested in the lazy loading feature using import. From the meteor night talk, they say that the Blaze templates are still global and cannot be imported (or lazy loaded), I have tried using React inside Blaze.
Added react-template-helper package using meteor add react-template-helper
Create imports folder and added testComponent.jsx file which exports 'TestComponent'
//testComponent.jsx
import React from 'react';
export default class TestComponent extends React.Component {
render() {
return (
<div>
<h1>TestComponent</h1>
<div>This is from Test Component</div>
</div>
);
}
}
After in the Blaze template outside imports folder,
<!-- homeReact template html-->
<template name="homeReact">
<div>
{{> React component=TestComponent}}
</div>
</template>
In the template's js file which is also outside of imports folder
// homeReact template js
import { Template } from 'meteor/templating';
import TestComponent from '/imports/testComponent.jsx`;
Template.homeReact.helpers({
TestComponent() {
return TestComponent;
}
});
This worked but the imports/testComponent.jsx is downloaded on the client (checked using chrome dev tools - sources tab), even if the current route doesn't require homeReact template.
Then I have used require instead of import like this,
// homeReact template js
import { Template } from 'meteor/templating';
Template.homeReact.onCreated(function () {
this.TestComponent = require('/imports/testComponent.jsx').TestComponent;
});
Template.homeReact.helpers({
TestComponent() {
return Template.instance().TestComponent;
}
});
This code also downloads the imports/testComponent.jsx file but in addition I also got an error
In template "homeReact", call to {{> React ... }} missing component argument.
So, my question is, is it possible to lazy load (download) files only when required?
