That's essentially what I ended up doing. I ditched the strap and then just aired it up and took the valve core out a few times over, while lubricating the tire again. Will definitely get some proper tire lubricant and pack a small amount in my tool kit. The front got up to about 70 psi. The rear seated with that great thunking sound quickly, but had to go up to about 70 psi to do it. I didn't take a picture of all of the patches I had to put on my otherwise new rear tube.Fwiw, the cargo strap used to be my method of choice seating the beads. Now I just use liberal amounts of soapy water and repeated airings all the way up to 60-70lbs if needed.
Air it up, bounce it off the ground, let the air out, add more water and then bounce the tire off the floor repeatedly all the way around to perimeter.... more soap and air it again. Even stubborn tires will succumb to that.
