from what i know: not really. FF sensor "should" have better signal to noise ratio. Cropping to APS-C size only reduce the amount of pixels available. It doesn't change FF advantage in the improved noise.
However, if they're in a pixel race and supply FF chip with pixel density to the same of APS-C density, you'll be right, since the whole thing would be pointless if all you have is DA lens. i have 2 DA lens.
