What CJ said. TS will definitely hurt bluegill size; but with two lakes, you can manage one (the bigger one) for trophy bass and the other one for trophy bluegill. For the bass lake, stocking TS and also GSH (golden shiners) will help the bass. For the smaller lake, stock it with a high density of bass, 100-150 per acre, and don't keep any bass, and install an automatic feeder or two and feed at least twice a day during the warm months. Do you have CNBG in the smaller lake? They're better for where you live because they grow larger - no advantage to northern-strain bluegill in your region. If you decide to make the smaller lake a trophy bluegill water, you might think about stocking two to four tiger muskie to thin out the bluegill so the remaining ones grow faster. Or, you could just seine or electrofish out a bunch of them and transport them to the other lake for forage.
