The M3's have a slightly different tone than the 5.25" woofered M2, M22. As CatBrat mentioned the M2 is the better match.

Are you talking about an on wall M22 and tilting that upward? If so the only way would be to build that section of the wall where the center will be mounted at the desired angle. The onwalls are meant to be mounted flat to the wall. This is the dilemma, lack of flexibilty of placement/mounting, when going with these aesthetically pleasing speakers over standard boxes.
