Mechanically the adapter for a 6008 professional or SRC 1000 should fit (an adapter for 6008 integral may depend on the removable film stage).
In case I had to do your job, I'd prefer the cheap&easy way: get a 6008 SRC 1000 or 6008 integral and proper adapter. My guess: a 6008 body is below 500,- Euro (compare this to the back's price tag!) - adapting the 6006 will produce more cost and less satisfaction.
