Could a "passive" ghost hunt possibly lead to an interaction?

(copy n pasted from r/paranormal) Me and my girlfriend are planning on doing our second ghost hunt on the same location. The twist is that we're gonna setup a table and 2 chairs and just play cards or a board game until we possibly get some sort of interaction. Our setup is an audio recorder, sony nightshot camcorder, emf reader, and a gas lantern for the ambience. The only issue is that the location is an 1830s church/ graveyard and I'm not sure if that would be disrespectful to play board games on a burial ground, even if on the path and not directly over graves. Any opinions are appreciated.
