Dynamic System.import with webpack?

I am trying to port some ES6 code I have written that uses systemjs + Babel.

I didn't have any problem porting most of the code.

However, I have some code that needs to dynamically load an ES6 module, like this:

function load(src) {
    System.import(src).then(function() {});
}

src is an external ES6 module which may also have dependencies (static imports).

How could I port this code to Webpack ? If I try to use require statement I'm getting a WARNING which seems to be normal according to the Webpack docs.
