I just did some reading online and found a scientific article on Moz T that said their northern limit is believed to be Gainesville, FL, which is two-tenths of a degree higher latitude than San Antonio. So according to that article, they would overwinter in San Antonio. From what I've read there are a lot of lakes in FL that are overrun with them, so I would be very hesitant to stock them if I were you.
Also, if you like to catch bluegill and are not just thinking of them as forage, you would be well-served to skip the GSH, as they eat the same foods bluegill do and will significantly detract from their growth. And they can take over a pond; there's a lake of over a hundred acres near me that used to have pretty good bluegill fishing, that I fished once this spring; I caught two or three small bluegill in a couple hours of fishing and dozens of GSH in the 8"-10" range. They have practically taken over the lake. And the bluegill are much smaller than they used to be.
