thereby increase the supply of SBDs which should hopefully put some downward pressure on the price.

I don't think it will put any real pressure though. As we saw last time, this is most like just a temporary thing. See aggroed's comment on that post for more details. I'm not convinced high SBD prices are a bad thing. We don't really have much of a market place going on in SBD terms right now and until SBD or widely distributed with a huge marketcap, it's unlikely we'll have a stable currency any time soon. I'd love it if we could, but unlike bitUSD, there isn't a mechanism to keep the price low (though conversions do help keep it from going too far below $1).

As for the impact, if you have SBD, sell it and enjoy the extra profits. Simple as that. :)
