This is an article on the Seahawks wanting to move down from the 25th pick.
For the 10th pick (1300 points), we would have to give our 2nd (450) 3rd (210) 4th (80) 4th (66) and so forth. Basically, based only on the scale of points, we would have to give up practically all our picks and we would still be short.
For the 25th pick (720), we would have to give up our 2nd (450) 3rd (210) and 4th (80).
Moving up to the 10th pick is probably very unlikely, but I could see it being worth it if we were able to get PP if he drops to 7th, and somehow either walk away with Dareus or Quinn.
Moving up to the 25th is more likely, but it would cost us 3 draft picks. A move up to the 25th spot would only make sense if the FO really likes a QB prospect like Kaepernick and are afraid they'll miss out on him in the second. I could also see a move up if there is a second CB prospect that they absolutely love.
I know many people here prefer to hoard picks, but who would have to fall for you to pull the trigger on that 10th or 25th spot?
