Main concern would be rate of air leakage at pressure. Only way to tell would be to mount it up and pump up to pressure and see if the leakage rate was acceptable over nite or a few days. If you have already checked the blown
tube for adequacy of repair use it for a spare while you check the repaired valve
tube.
I rode a tube that leaked 5-10# hour for awhile before taking time to pull it and
find the pinhole. OK for short rides.
