I just tried it and the center image is very good. It's not like the sound is collapsing into either speaker.
I will tell you this though. I had M2OW where the M5OW are. When I sat on the couch, anywhere from mid-point to the end furthest from the speaker, I could clearly see the center image. There was barely any image collapse into the left speaker. I can't say that about the M5. Adding the mid-range driver messed with some of the off-axis response. I suppose the M2, within its specified operating range, is more linear than the M5.
That won't be a problem for you though and for 2.0, M5 is a great way to go. M2 may sound a little thin without a sub and if cranked up, they will distort if they're not cut off at 80Hz to a sub.
