I’m fitting a ‘gravity feed’ hot water tank in a mobile home that has restricted head height for a cold gravity feed header tank. I can install an expansion over flow to an outside drain. Is it possible to use a Pressure Reducing Valve to supply the cold water from the mains supply. Or is there any other way to supply the cold.

You'd be better with an unvented cylinder or small hot water heater..... You'd need someone G3 qualified.
But short answer is no, you can't do what you're thinking.
