I have installed the configuration you speak of. It came out very nice. no sloped ceiling though, just standard 8' flat ceiling. These were 4" old work recess lights..i put 3 over each couch, and then 2 4"eyeballs about 2' away from the fireplace. Each set of 3 lights had their own dimmer switch as did the eyeballs over the fireplace. This installation was for my parents who are getting a little older, and needed some good reading/knitting lighting. I wish I could send a picture.
