And if you're comfortable *writing* kernel code, I would suggest implementing WORF in geom_mirror :)

I am intrigued, what is this WORF you speak of?

Write On Read Failure. It means that if you can't read a sector but you have (or can recreate) a copy of the data that's supposed to be on it, you rewrite that data to force the disk to reallocate the sector. I've done this manually several times (dd'ed a sector from the other disk in a mirror). I believe I even posted the procedure at some point; I'll check my archive.
