The only issue you may have is your 8 speed chain interfering with the 52T ring when using the outer portion of your cassette when in the 36T ring. I experienced this before using a 9 speed crankset with all 8 speed components. However, it was a very small frame with short chainstays which exacerbated the problem. Worst case, you can swap out the chain for a more narrow version to reduce the interference (though this might require a new FD, too, to keep shifting satisfactorily fast).
