One thing I'd like to see, since I find some of the retake battles a bit too one sided if you get bad luck with draws is hiring someone to retake the area for a reasonable amount of money or "other" things. Though that's mainly because I always felt a bit too punished for opening rooms early so the new characters might make this redundant.

I'm introducing the ability to swap cards in your hand with random ones from your deck in v2. You'll be able to do this before the first round begins and at the end of any of your turns. This should make your decks more consistent.
I don't oppose offering the ability to pacify the rooms for money either. That might be something I'll look into adding to the game in the future.
