You don't need to go to that much trouble. I can tell you that at the very least there is not a wonderful relic in all of these rooms. It's possible it leads to one. But all you need to do is go into buy mode, and with testing cheats enabled, shift + click on each treasure spawner or chest or hole in the wall and see it's treasure components. I think it is more likely about the door to the void, though I haven't seen doors on some of those rooms either (to the void, that is).
