The alcohol may raise whiskers and will swell the stock more because it attracts water and usually has some in it to begin with.
My experience, which is limited to 3 or 4 stocks is that they return to original size. I would not work on the stock until you are satisfied it is done shrinking. I have found that I had to soak three days and in one case I had to do it twice to get all the oil out.
Be careful about previous repairs since the glue will be dissolved. I don't know if epoxy is affected but most other glues are affected by the acetone, alcohol and the inevitable water (even in small amounts) in the acetone and alcohol.
