You could go ahead and do the conversion now. I imagine in Texas, you still have quite a bit of swim season left. The conversion shouldn't take more than a week and for some people who test and add bleach every couple of hours, their conversion takes only 4-5 days. I wouldn't use some magic potion during conversion - but only lots of bleach! It's a tried and true method as many people here on the forum who have had successful baq to chlorine conversions can attest to.
