Eeehee, I really like this! Not only a fabulous idea for a crossover, but also so well done. Both the characters are wonderfully spot on, and it's a nice contrast seeing Will, "immovable as a mountain", with Rose and her irrepressibility (not sure whether that's a word!): Rose started laughing, and hadn't stopped for a full five minutes. "God! That is such a relief!" I can absolutely imagine her. Seeing Will and Kirjava at the end is lovely, too, with the nice bittersweetly uplifting ending, focusing on moving on from the past. I also can't help wanting to see how Rose and Mary Malone would interact!
