If you really like the clarity of the M22s then you will need to go with the M80s alone or with the M22/M60 combo. The 60s are not as articulate as the other 2 but adds a very nice warm rich sound to the lower end but still allows the M22s to shine through in the upper range.
With your setup the M60s could be placed directly below the M22s and the soundstage would be seamless. My setup for the M62 is less desirable as my M22s are about 6" inside the M60s and 6" above them, but it still works exceptionally well.
