Lost In Time has a slightly different background - the Alt Clark we know but Lois was never at the Planet.
I keep thinking I remember hearing about one - dunno if I ever read it because I'm thinking it may have been nfic and I don't know if there was an nfic version - but someone told me about it once and I remember being intrigued but I don't know that I ever read it. Alt-Clark ended up in a 3rd universe and Lois and Clark and Alt-Lois end up in the 3rd universe and then in a 4th...
I know there's others... but I'm still blanking.
