I did end up running this and we had a great time! It was a little tricky managing the threat of the hogstorm, since the group became very interested in specific details of each encounter and setting... but I ended up being lenient (mostly) and it worked out well. Everything ended fairly spectacularly on a church roof that was very much on fire, and there may even have been a few sparks of unexpected friendship between Lady de Grope and Mr Wickle.
It was the first time I've run a Blades in the Dark system, so I found it a bit challenging to manage position/consequences, especially for partial successes. Overall, though, it a was a really smooth and fun experience - the players loved it.
