If you are seriously after a Carbon blade, You can either
a ) Wait for RTP's Carbon spoiler, or hybrid FG and CF
b ) Wrap it like what Mikey did.
c ) or Finally, Something called Carbon Skinning. This is not commonly done anymore as CF Vinyl wrap is easier to do. But you do get that Shiney Lacquered Carbon look. So in basics, You get a sheet of real carbon, stick ontop of the FG blade, and lacquer it. Not really sure what the exact process is, But that's it, Plus probably lot more complications in the matter.
A real Deal spoiler is indeed pricey, But thats TRD goodies for you...
