I don't find that your copper sphere pendants work with anything currently in your kitchen. Are you sure you want to head down that road?

Seems very unusual to have a line of recessed downlights and then pendants in addition to the downlights.

They are the shiny version of the above

The touches of black make a black fixture a good idea.

Or you can try to complement the copper. All of these chandeliers are on Build.com .

Do you love the copper or just don't want the expense of replacing them all? Taking them down (as already mentioned they seem like over kill on the lighting) costs nothing and a larger dramatic fixture could replace the one over the table.
