without seeing pictures of the existing space, that's a pretty hard question to answer... If you are looking for more light there are many ways to accomplish that depending on existing conditions. My guess is that the wall to wall mirror makes your living room look much bigger and that without it would be an issue. My first question would be why don't you like the mirrors? Is there something new that can be done to incorporate some trim to break them up a little and create more interest because possibly you don't like the look of them as they are now? Hope this helps.
