I've never heard the M50s, so I'll not be much help.

Some here prefer using a regular speaker as a center, but I think most would advise NOT placing them on their sides.

In addition to the answers you get here, may I suggest that you email Axiom's resident expert, Alan (alan@axiomaudio.com) and ask him the same questions. He's a good guy, and he'll give you the straight poop about timbre matching and using the 22(s) as centers.
