You maybe able to adjust the spacing between the Specialized rings to 11s chain width spec. You will have to do some research on that. Not a bad idea to email Specialized tech department. They will respond and believe if you ask them about installing Campy cranks on a Sworks they will tell you they are incompatible which they pretty much are. Campy cranks are pretty unique in that spacing can't be changed because bearings are pressed onto respective spindle halves...unlike virtually every other crank out there.
Yea, I was kinda upset after I bought I entire SR 11 group just to find out that the cranks were incompatible. I found a set of new 2011 Sworks cranks 172.5 53/39 for $300 shipped. They get here tomorrow. So now I have this super cool SR 11 Ti spindle crank.. Maybe I'll hang it on my wall like a $1000 piece of art.
