I am surprised you are looking to mount M22 side ways like that. I would think VP100 or 150 in walls mounted horizontally would be the preffered choice as the M22s will not have quite the same dispersion when mounted side ways. I will guess you already had the M22 in walls and this is a reno project? Any way be sure to try the M22s with the tweeter's on the outside and then on the inside and go with which ever sounds the best.
