Ooh, fun! I, too, love those bait and switch -- or actually, switch and bait -- stories.
As for other stories that switch a married Lois or Clark with their unmarried counterparts. Most recently, there's been Ricochet by Sue and Forshadowing by Happy Girl. A bit older are Kipp's Switch and Not Again, both in the nfic section. Also a mention worth is LauraCH's Another place in Time, also an nfic. I'm quite sure that I'm missing a few others that also use this theme. I recommend starting a fic-search in the Fanfic Related folder.
