The fifth book of Sarge4's Ranmafic Queen Rat http://www.fanfiction.net/s/2518671/47/Queen_Rat introduces people who are not the Sailor Senshi. But they're close enough that Sarge has to keep reminding us they're not.
Really, he's taking similar girls with the same names, and forming them into a Nerima-type group called the Fallen Angels. It's been an interesting look at the Ranmaverse, and now the story includes a kind of mutant Senshiverse. Lemon/lime warning.
