I think you are on the right track with the inversion idea, however you would need to have a real time unit doing it as it would be impossible to have a recording keep up with the constant changes in sound over time as factors such as; air temperature, pressure, humidity, the fans mechanical aging, how many people are in the room, rearranging of furniture, adding removing rigs, and on and on would influence the sound being produced at any given moment.
I used to play around with electronics when I was younger and I recall it wasn't that hard to make a audio inverter. There are some professional speakers that will also invert a signal, but perhaps you could head to your local guitar or music store and see if they have something ready to go to save you a bit of time and effort. However, even with this setup it will depend on where you are in the room compared to your miner and speaker placements for the maximum damping to have effect, as elsewhere in the room or perhaps further out in the house, the sound waves will reinforce each other thus amplifying the effect.
In the end, while it may work, it may just be easier to try and relocate the miners to a room you are not using or to a removed garage or shed if possible, or as you suggested but didn't want to explore a sound isolation box.
