Does the Rococo series and Gorgeous series look well together? If so, then why not use both in the room? Just a suggestion!
Personally I think their styles clash too much. They might work together, but it will probably be difficult.
If you want a good series to mix Gorgeous with, I find that the Sleek series works really well. As for the Rococo series, there are a lot of various items of no particular series that I think can go really well, such as the vases or Museum set.
There are options of refurbishing.
