To answer your OP - afaik, no.
And in addition to the 2 stackers above who will take your bitcoins, you can also try
this one
Like anything, a price needs to be agreed in order for a trade to occur, so pricing of the silver/gold and the current rate of bitcoin needs to be established and agreed else a trade will be difficult.
The price of Bitcoin is currently under $50 AUD yet its probably hard to source for under that.. conversely.. in that trade would you trade spot for spot.. or with the premiums that come with physical silver.. anyway these factors make the trade a little more tricky.. with compromise and good trading methods its actually easy.. and you only need one buyer/seller to sell a deal.
