seems to me that you'd be unnecessarily stressing the tube for no reason doing that. After properly doing the submerged check, with enough pressure (teeny tiny holes have always shown up for me, with enough pressure and being very attentive and going slowly) just put tube in tire and monitor pressure with a gauge.
