The pieces needed to build a Metru blue version do not exist, unfortunately. I would recommend using the pieces in black and adding black into the color scheme. Alternatively, if you have any of the obsolete dark grey liftarms from 2001 or can get some off of Briclink, then I would recommend painting them. :P That's what I'd do.
