I thought about it after the fact you may need extra cord for desired height but what you showed in the picture will make it easy enough.
Another possible suggestion came to mind based on your picture. Check out the link below. Only for subject refrence. It would make the cords stand out a little less, somthing like these. Double side tape to wall possibly. They also have stuff like this at lowes home depot etc.
