We have got some Regency era CAS/BB with R&L and LBMB kits. But more Victorian leaning could be expanded, as most of our Victorian CAS/BB is from the Vampire pack but not exactly the best for transitioning era play vs. decrepit and Vampire play (since limited swatches).
We could really have a Victorian update/addition with still some Regency cross over. I think these are popular and wanted. Some people bought the Vampire pack just for the BB and/or CAS. I'd love a downtown Victorian heart of the city neighbourhood.
