Unfortunately many of your Maples will not tolerate the Southern heat of Georgia. Although many are rated Zone 7 ( Northern Georgia ) bark splitting, and leaf scorch make them unsightly.
Now the good news, you should be able to grow a number of Oaks such as Bur, White, Swamp White, Live,and Shingle Oaks.
Also a new Birch Variety 'Dura-Heat', any ornamental Pear, or Crabapple, or Flowering Cherries also.
Hope that gives some ideas.
