Such a material would, by your very definition and every law of physics I've ever heard of, have a valence configuration and nucleus identical to gold and, therefore, would BE gold. It would be more reasonable to imagine some new process by which we cheaply convert another material into gold and flood the market.

It's also noteworthy that simply matching one industrial quality isn't usually enough. Silver, for example, is a much better conductor than gold - unfortunately it also tarnishes easily which ruins its conductivity. Find a cheap and easy way to keep silver from tarnishing and you'll see store shelves flooded with silver-plated connectors very quickly (considering its cost relative to a similar quantity of gold).
