Has anyone ever written a Ranma and Marmalade Boy crossover?

For some reason, I just couldn't get the idea of Akane taking
Miki's place and Ranma becoming Yuu(with curse intact). Ranma
and Akane have to live together because their parent's decided
to switch spouses(there is no such thing as stepsiblings in 
Japan). 

Shinnosuke becomes Ginta(Miki's old boyfriend from jr. high). 
For the cause of their breakup, instead of him saying he didn't 
love Akane to his friends after they found the love letter she 
gave him, Shinnosuke forgets who she is ^_^

Well, that was just an odd thought I had.
