Given that the formula is  conv_out = input *correl* weight + bias (*correl* being the correlation operator), this will not change the ∂conv_out / ∂weight nor the ∂conv_out / ∂input. It will flip the sign in ∂conv_out / ∂bias. It will almost certainly change ∂loss  / ∂conv_out as that now is computed at a totally different location.
