This would actually be a net improvement, though it might take a while to clear sufficient amounts from the atmosphere to be noticeable. Unfortunately, it would possibly increase the amount of free CO2 for a while.
Kind of a pipe dream anyway, though. You would have to work on a truly enormous scale to tilt the balance even a little, and even then, the landscape isn't exactly inviting.
I think the precipitate should absorb the atmospheric carbon and upon settling dissolve to release a water byproduct. The continued introduction of this imaginary precipitate would still lessen the atmospheric carbon dioxide. The sulfuric acid would dilute. Ideally the imaginary limestone-like precipitate would be created from the compounds already in the atmosphere, just needing some small catalyst to get it going.
I think a lot more study needs done before I'd be willing to support interference in planetary processes. We've already stick fiddled up things here on earth; no need to replicate that elsewhere.
