How about one where she arranges to have Nodoka killed, and Ranma sees it... and has to deal with the fallout of a enraged and determined Ranma, and a curious Ami whom does not understand how it came to this?

The problem with your request, is if you keep them in character, the NWC would be half for, half against, such a act. And no matter how you slice it,t he ones that would be looking for revenge would likely be the weaker of the lot. And would they be able to take on multiple Sailor Senshi? It would be hard to write at best.
Also... from the Senshi's standpoint... no true fan I've ever encountered of Sailor Moon would want to write Usagi having to deal with such a angle. And personally... if using anime continuity, am doubtful she could deal with it, or at least deal in a manner as it should.
Most stories either take the viewpoint of Ranma dealing with the equivelent of a assasin (using his likely terminology) like Phoneix Ranma, or the viewpoint of one or more senshi attempting to figure out why she would do so (XZero's story for one). Or the cliche he is a threat to the timetream/future tokyo and normally follows the outers as a group with sometimes the inners joining.
Another type of take would be a Ranma/SM/Wheel of Time triple crossover with Ranma being banished for 10000 years and Akane and others coping while no one believes them.

Most do not generally eal with Ranma as being dead, and those that do, normally have him elsewhere but believed dead, not dead.
One interesting reverse take on this to come to mind... What if *Moon* kills Ranma (or believe they do in any case), and Pluto was in love with him, and had to deal with the fact they killed a good guy... Try:
