If the spokes are chewed up but otherwise still doing their job, why don't you just leave well enough alone.
The wheel is OK now, and it's theoretical life is compromised somewhat, but who knows by how much. It might last hundreds or thousands more miles before any of these spokes actually break, or then again you might drop it into a pothole and dent the rim next week.
My point is that unless you're going on a long trip where reliability is at a premium you might as well continue riding this wheel, and replace the spokes one at a time if and when they break. You have absolutely nothing to lose by riding it, unless you go miles from home, so you might as well use it as is.
