Thanks so much! I agree, the crossover possibilities with these worlds are neat. I'm only aware of a few other stories myself (and I can go back and read them now; I stayed away while writing this!) but I think there's lots that could be explored.

Heh. I must admit I haven't seen past episode 6.5 yet, so I haven't seen the soulless revelation or subsequent events! (I did get spoiled for it eventually though.) So, I really wasn't thinking about trying to fit in that canon, and it's great to hear that it works out regardless. :)
