There have been a few Tempus Fugitive's, I think, and I doubt that I'm the only person who has had a go at Resurrection.
Curiously, I think the episodes that have been rewritten most are favourites. With a few noticeable exceptions, it seems to me that the least popular episodes get left alone. The Argh! and the New Krypton series are (IMVHO)... flawed (now, there's a tactful word!), but they have redeeming features. (In the case of NK, it's the angst. If only you could remove the New Kryptonians, themselves!)
By contrast, my impression is that episodes like Ghosts don't attract rewrites. (I'm willing to be corrected though, given that I'm so behind on my reading!)
Oh, and I think some people have had a go at Soul Mates, though whether those count as rewrites or sequels or what, I'm not sure.
