I'm wondering if anyone has had the idea of laying down a thick nickel plate (over copper if required) to give good corrosion protection then following up with a fairly thin cobalt plate to give the blue (as opposed to yellow) shine that will duplicate chrome? This would of course be very much the way real decorative chrome is used, over a thick nickel base plate which imparts the actual corrosion protection with the chrome only used to give a visual appeal (chrome being more blue than yellow tinted).

I would think this would give you a visually better part as compared to CopyKrome, which is a nickel/cobalt alloy. Using this two step process you would end up with all the cobalt on the surface layer which is where we really want it.
