Yeah drop at least one belle and replace it with a nurse, nurses are really good, i have one in every list, a fast bishop with +2 damage to Ml attacks is deadly. I'd recommend maybe dropping a second belle for something else, 1 should be enough unless your opponent has a habit of focusing belles. I'd also think about dropping Sybelle, i don't think she's worth her points outside Seamus or Molly. Maybe take the emissary to speed up your crew and block LoS, give Sonnia a taste of her own medicine.
