I did the same thing. I had one of those rooms open to everywhere. I had two sets of french doors installed. They work just fine. It was important to me to let light through and also retain the sight line through the house. The doors can be opened all the way to accomodate the open flow through design that was originally intended.
I don't find the sound leakage any greater through the room with the french doors vs the standard hollow core interior doors in other rooms. You don't state if soundproofing that room from the remainder of the house is a priority. I think the french doors are an elegant solution. Check my system for photos.
