Using 2 of Centers as Bookshelf Speakers.

I'm using a brand new (less than 10-hr) center Focal Chorus 800v ($400) for my 5.1 home theater, and it seems to have the body and warmness that I like. I'm curious what would it be if I purchase another one and use both as my front bookshelf/monitor for 2-ch listening?
Center speakers are strongly concentrated on voices & mids, so will they be very well wking together to get great soundstage, image, and disappearance?
Any1 done or gone this route please chime in.
