Well, I can find a story that fits the Senshi thing w/ an evil male + good female reincarnation, but the male side of Ranma doesn't die.
Chaos Moon by The Eternal Dragon, it is discontinued to the best of my knowledge.
At any rate,
Gin and Kin by Materia-Blade kind of fits the dead-male Ranma motif. His male side isn't truly dead, but it is effectively dead because Ranma will die if he turns back male. It is a SM/Ranma cross, but it has been discontinued. I can't really remember much about the story though.
