After some consideration, I decided to "downgrade" my dual projector setup into triple screens. What I realized during this year, when I had less time available for gaming, was that when I had time, I would have had to calibrate the projectors and ended up doing something else. Biggest issue was my room: small room with low ceiling in an old wooden house. The projectors were mounted on the ceiling and if they moved even a bit, I got ghosting into the seam of projectors' images. Perhaps I could have built some sort of frame for projectors, but with small room, it (or third projector) would have been a challenge. So I ended up putting my projectors for sale and picked three 75" TVs. Based on a quick test, the small loss of immersion doesn't matter that much.
