Rolls eyes, given how often it has been brought up, I actually regretted posting in that thread. I've been PM'ed a couple times on it, and that thread even came up once on the TFF forum.
The simple fact is there are tons of them, and I never really considered them all that hard to find, thus my non-interest in really pursuing posting more than I did. I did warn though, the grand bulk anyone finds will be older stories due to the lessoning popularity of that crossover.
Here is another.

Technically the following is a sort of matchup, but I really do not count it.
RANMA-SM 'Saturn of the Amazons' by Riko Tenachi - [Dld Date=08/08/2003] - [Dld Size=40kb] - [Dld File Cnt=2] - [Dld Status=Inactive]
Not one I track, but one I've been aware of for awhile:
RANMA-SM 'Sad Times, Happy Endings' by James ThomasAlso not one I track, but another one I've been aware of for awhile:
RANMA-SM 'Ranma and Hotaru An Insert for Turn the Page' by Christopher AngelThere are also some with Ranma as a sibling or parental or bodyguard/guardian type figure in her life. Including one ancient lost Anifics forum thread adventure that was a experiment at AA type adventures in a forum.
In the AA threads of GateKeepers 1/2, Gate of Light, and Gate of Light - Lightwings... she is a sort of obsessed fangirl of Ranma's. Not sure that classes as a matchup though.
There was one on MediaMiner where they both Run Away separately, but meet on the road, though I can't remember the name offhand.
There is also one I came across a long time back, where Ranma, through events, ends up as a sort of El Hazard Demon God... and is resurrected by Professor Tomoe and is to act as Hotarus Bodyguard and confidant...
I know of at least a few more... I'm just not interested in posting more on it.
