Let's say Hank doesn't hurt his back again in 1951, and so doesn't end up with as severe a drug habit. Maybe, in keeping with the Luke the Drifter persona, he even ends up drying out a la Johnny Cash. Where do things go after that?
Say he goes to an Oral Roberts crusade meeting in the mid 1950s and his back gets healed. That butterflies the drugs and alcohol or he also gets free of that at the same time as his back getting healed. He gets born again and starts leading worship for Oral Roberts. Richard (Oral's son) and Hank Jr become friends and the familial friendship keeps the sons from some of their darker points.
