Once upon a time, there were the DC-8-61 and DC8-63 which were stretched several over 36 feet to a length that looked ridiculous. They put a hardpoint under the tail which could drag on the ground if the pilot overrotated, which was VERY common on that bird. (Also, sitting near the rear in turbulence was sphincter tightening as you could see the fuse was wobbling at least 6 feet sideways in random directions.)
I flew in one to France in 1973, and it dragged the tail *hard* on takeoff: There was no damage because of the hardpoint.
So if tailstrikes are a problem, quit screwing around and put a hardpoint there to protect the aircraft. If it worked on a DC-8 40 years ago, it can work on a piddly little 737 now, FFS.
