I say go for it Sall! It is so freaking hot in Texas no matter where you are that humidity actually helps in my opinion. The only time of concern would be dormant winter months that you would have them indoors in a controlled environment anyways.
But.... on second thought in your region depending on your own micro climate where you are it might be possible to keep yours out all year unless dramatic drops of winter coolness below norm and you keep protected from to much winter water while dormant.
I have had to protect way too many of my hardies this year from the sun due to massive growth from abnormal rain in spring and then can no longer withhold itself when normal conditions arrived this summer meeting the extra growth needs. That has been a first for me, but so has 23 inches of rain in 28 days. It was more than that but that was when I stopped counting.
Get some! And then post pics of course!
