Of course the SRAM blurb says it won't work without the yaw FD but it's got to work, hasn't it? Would the chainline be out of whack with a GXP BB?
Depends what you mean by *work* and whether you are waranteed, and if you are, whether you are bothered about maintaining the warranty.
It's doubtful that the shifting will be in any way optimal - SRAM's ramps and pins are designed to work with SRAM chain and FD, not Campagnolo's, SRAM ring spacing is also diofferent, plus the "yaw" motion of SRAM's FD puts different amounts of force on the chain than does the Campagnolo FD.
Chainline (which likely falls into Campagnolo's tolerance as it is a function of rear drop out width, cassette width and cassette placement relative to the dropout) is likely to be the least of your worries!

Thanks Graeme, I've just seen you replied to my thread from last week about the 'bent' hirth joint (these two threads are somewhat related as I'm looking to replace that crank with something I can use with a Stages power meter). Maybe one of the FSA options would work better tham SRAM.
Anyway I'll send the crank in for a look over.
