Is it okay to do CoolSculpting AND ultrasonic cavitation?

regardless of how much I diet and exercise, my lower abdomen never budged below 32 inches. I want to get the Coolsculpting procedure to elimate some fat cells, and a few ultrasonic cavitatios to help the remaining stubborn fat cells release the fat it seems to think necessary to cling onto. Should there be a gap period between procedures? Will the Cooled fats be melted by cavitation? Thank you
