There might not be many about him with his others (sorry David, didn't 

mean to cut that section,)
but December's End, Visits & Revelations, Elseworlds 1 (has Ranma liking 
Ukyou), Ryoga:Crossover (has some scenes about Ryoga married to various
cast members), I think Parallel Lines and Pulp Fanfiction, Descents and 
Inversions, and I think that's all the ones I know off the top of my head,
all have either Ranma engaged or in love to someone else, or display the
possible children of the marriages. :)<<

I wish to point out that all of the above ('cept maybe Visits and Revalations) have alternate timelines in their plots. In all of them, Ranma was only married to one person in each timeline. The Road not Traveled is unique in that it shows Ranma marrying all three of them in the same timeline. 
It's a pity that just when fanfic writers think they have the future of the Ranmaverse in sight, Takahashi Rumiko throws in a new character that wrecks the old status quo. Certainly the introduction of Akari and Konatsu have made many past ideas for pairing off characters in the the Ranmaverse obsolete. 
I doubt there could be more new characters introduced. But there might be one more psychomaniac for Kodachi, or maybe another man for Shampoo whose a better match for her than Mousse (not likely IMO).
