When you're touring with 15-25lbs of gear on a 20 mile 10% grade, that ratio sure comes in handy.
It would be easiest to pay the price for a 5 speed freewheel with expanded gear range. Otherwise you're talking about respacing or replacing the rear wheel and respacing the rear triangle to use 126mm spacing to fit modern kids bike 6 and 7 speed freewheels in there. You'd have no issues with the shifters, but you might need a new rear derailleur for it to work well.
