Other than the bling factor (which is a legit excuse), why are you thinking about this "upgrade"?
Does it have anything to do with changing the feel of the front brake?
if you're looking to make the front brake less sensitive, the consider going with a 19x18 master cylinder. Or better yet, take a look at the brembo that has an adjustable offset ratio.

You'll need a brake switch too.
Hand guard clearance and resivour mounting will be issues.
