Your lenses are fine, but your choice of format (cropped sensor, and D500) leave something to be desired as you are finding out. An FX body will give you better low light performance, and both the 24-70 and the 70-200 will be a great choice. Get a D700, or better yet, find a nice clean D810 - you'll be glad you did. What you don't need is another lens.
