Love the frozen VO paint job. IMHO, VO is a hard color to match in terms of having any other colored accents( stickers/ calipers / rims etc) apart from black..
Maybe you can try a subtle approach. Use a gloss transparent sticker to make the decals appear gloss vo on a matte vo surface.
I've done this on my matte gray car b4 and use gloss film for the decals. Subtle without having to introduce another color
Try to get some pics up later. Nice car BTW.
