Campagnolo rear mech with Sram groupset
No. it won't shift correctly - SRAM must be used with appropriate SRAM levers, Shimano with compatible Shimano levers, Campagnolo with compatible Campagnolo levers.
Each manufacturer has their own ratio for cable recovery to derailleur movement, each company has their own strategy for coping with the fact that the angular movement of the chain sprocket-to-sprocket across the range of the cassette has to vary slightly.
Shimano and SRAM manage the latter mostly in the lever, Campagnolo split the management across the lever and the cassette spacing, which contrary to most internet chatter is not the same as Shimano / SRAM and nor is it constant.
