Ok... here are a couple fanfic crossover ideas I had:

1. Sailor Moon\Ranma 1/2
My idea here is that when Queen Serenity battled the dark moon and used 
the silver crystal, when she sent her daughter and the Sailor Senshi to 
Earth... they ended landing in Jusenkyo and drowning in the springs... 
somehow they were cursed so that if the dark kingdom ever threatened the 
universe again the worlds most powerfull martial artists would end up at 
Jusenkyo and fall in one of the springs of the drowned senshi (no one 
will ever fall in unless there is a threat from the dark kingdom)...
One thousand years later... enter Ranma.. While training at Jusenkyo with 
his father he falls into one of those springs (spring of the drowned 
Usagi).... you know what that means.

Particulars of the curses:
-the curses are psychological as well as physical... while in cursed form 
the victim is basically taken over by the spirit of the senshi and 
experiences what is happening in a dreamlike state.
-the cursed form is the senshi in their normal or untransformed state 
(ie. Usagi instead of Sailor Moon)
-the cursed form retains some of the normal forms abilities (ie. Usagi 
can perform some of Ranma's martial arts moves... but she is also just as 
likely to dodge a blow or land a hit on an advasary by klutzing out.)

Ideas for other characters:
Ryoga=Rei/Sailor Mars
Mousse=Ami/Sailor Mercury
Genma=Luna??


2. Star Wars\Ranma 1/2
Ok the idea here is that one day a stranger shows up at the Tendo Dojo. 
This stranger flies a strange shaped aircraft, is always followed by a 
barrel shaped robot, and has a sword with a blade made up of light. The 
stranger introduces himself as Luke Skywalker and says he is following up 
on rumors of people with strange abilities showing up in the area. When 
Ranma gets into an arguement with Akane and gets thrown into the koi pond 
Luke notices that Ranma's female half has force potential and after 
hearing the story of Ranma's curse theorizes that the girl who drowned 
in the Nyannichaun was either a jedi herself, or somebody at least with a 
lot of potential... Luke offers to train Ranma in the ways of the force 
and soon finds himself wondering what is more terrifying... the Galactic 
Empire, the dark side of the Force, or Ranma's fiancees...

------------------
Well those were a couple of ideas I have for crossover fanfics (If you 
don't like them... well I didn's say they were good). If anybody actually 
decides to use one of these please let me know so I can see how it turns out.
