It may be half assed, but I can't see how two regulators would conflict with each other. The return line on the front regulator is blocked off, so it can't affect anything.
What you need to do, is use the regulator that the ECU was designed to work with. Returnless systems have constant pressure, and systems with a vacuum hose on the regulator vary the fuel pressure based on engine load.
