You might take off the gold borders and then split the wide plain ones (in half or even thirds) and put in something you like better, or that matches what you already have. It would use up that white, not require as much re-doing and that gold could be used elsewhere. (It does not seem to go with the rest of it?) Even the gold in the middle (at the top of your photo) would be minimized.
Funny how tastes change, isn't it?
I'll be interested in seeing what you do with it!
Sounds like others agree with this idea...
