Turbine D I am not sure how long it would take to pump the quantity of fuel to the center tank from the trim tank to equal a 24-26% CG. Tubby gave an estimate of the amount of fuel in the trim tank in his post #1253. However, that said, it could be pumped back to the trim tank after the perceived turbulent episode was over to regain the desired efficiency. Perhaps one or more of the A-300 pilots could comment on the pros and cons of this idea.
PJ2 once kindly returned a comment to this question:
.......There are no procedures established to move the CG forward to "guard against stall" - in fact, no airplane which would require such an intervention should be flying as a commercial transport.......

not shure, but it look as if needs a longer time to pump all the fuel of the trim tank forward 15-20 min
the volume of the trim tank is 6230 l (4890 kg)
