12 oz of oak chips is some serious oaking! The good news is that oak flavor tends to mellow out with age. If you added the oak to your primary (it's difficult to tell from your posts what stage your beer was in) I would allow 3-4 weeks for proper oaking, then rack to secondary for at least 3 months to allow it to mellow. Since you said you already plan on bulk aging for ~6 months, I think you'll actually lose most of the oak flavor in that time. With 12 oz aged @ 6 months, I think that might actually work out quite nicely for your beer.
Please do let us know when it's all said and done. I think it will turn out delicious, and am interested in the finished product.
