Mdhoover,
I see no issues with what you have....edge diffraction can become a problem with anything too close to the speakers but that does not appear to be your case.
If you don't plan on ever moving, are getting rid of Gladys anyway, and are prepared to stick with your speakers over the long term then you might consider custom build.... a soffit mount built in wall design....just use lots of MDF (2 inches thick and make sure it is all heavily braced)
Good luck!
