Interesting idea, Jeff.
Before I remodeled my bathroom several months ago, I also had a 1960s valve with separate hot and cold handles. I dealt with the scalding problem by just setting my water heater at 120F and then only using the hot lever in the shower without turning on the cold side. The downside is that with the lower water temperature that we would run out of hot water sometimes with back-to-back showers.
same concept, but this would only lower at the shower. Some people never fix things , and others cant leave anything alone. I wouldn't waste my time on this with pressure gages or repipe though just change the valve , turn heater down , or try something like i suggested or kinda think it through a bit more but I think it would work
