Yup, This is almost exactly what the BL Metro turbo does. It was 
carbureted and was a blow through set up so the Carb float blow 
had to run at boost pressure. SUs don't like to see more than 
about 4psi across the float valve so they had to reg the fuel 
pressure to to 3ish psi above boost. The pump pumped fuel up from 
the tank then the reg passed what the carb asked for and the rest 
got returned to the tank.
 
I have seen inline regs but I don't think you could reg 50psi down to 
7psi with one of these.
