I doubt that would work well, unless your DAC has essentially perfect jitter rejection.
S-video cables conduct two separate high frequency signals (luminance + sync, and chrominance), and have two corresponding return conductors. Passive S-video to rca adapters typically just pass the chrominance information through a capacitor and then sum the two signals together.
That kind of arrangement is non-ideal even for its intended purpose of S-video to composite video conversion, and for a 75 ohm digital signal would essentially result in a mess in terms of impedance matching and waveform integrity.
