If it were me, I'd just salt them a little more and keep them in the frig rather than re-freeze them. Just for fun, we kept brined bait over a month last year in the frig and caught nice kings on them all summer long. I think fresh is better, but I'm not afraid to use older brined bait as long as it's been kept cold.
