DIY fuel return restrictor/pressure increase?

Just wondering if anyone here had come up with/tried a DIY fuel pressure increase by restricting the return line.....
It made sense to me that you could place a small flow restrictor (such as perhaps a small metal shaft that had been centre drilled) inside the fuel hose on the return line. You could hold it in place with a hose clamp, and is would effectively reduce cross sectional area inside the hose, increasing fuel line pressure.....
Or would it be negated by the stock FPR????
I don't know the maths off the top of my head, but is there anyone here who could work out how much reduction in CSA you would need?
There is a similar small white plastic restrictor inside the hose on the tapped cover breather hose.... that's what made me think of it.........
