I hear parts of FL are experiencing some actual winter weather, so maybe a road trip is in your future? Nothing like real-world testing!
But in actual answer to your question- it may work for fine you.
Are you planning on using the pad in the hammock as well as in shelters? This may not be applicable to this area of the trail but it is worth thinking about.
Some people sleep comfortably with a pad in their hammock and a top quilt/sleeping bag into some pretty chilly weather. I personally found I need an UQ when hanging in the cold both because I sleep very cold and need the extra insulation, and because I squirm in my sleep and a pad ends up halfway out of the hammock quite quickly.
