Justin and Miley in Grease Remake?

In a recent interview with a British newspaper, Justin Bieber was talking about possibly starring in a remake of Grease alongside Miley Cyrus:

"It would be a lot of fun. It's been talked about a lot over the years but it would be awesome to play Danny."

When asked about a possible co-star Bieber said:

"I would go for Miley Cyrus without hesitation. She can sing, dance and act...I'd want some great people to star in it."

So I guess the question has to be, is this something that is really being planned, or has Justin Bieber's imagination run wild? I'm guessing that it's pretty much a long shot that something like this would actually happen.
