Oh yeah, it's a rather easy modification. First pull off your front panel and look at the mounting for the led's, screw mount, glued in, removable at all? Most likely the led's will be 5mm (3mm are sometimes used) and glued in (most common method used) with hot glue - they're usually fairly easy to remove, you'll need to secure the replacements with the same method if possible.
And then the hard part, purchase this
