Sorry for resurrecting an old thread, I have dual flashing front lights, one flashing rear with brake light function (Cateye), dynamo front and rear lights, I will soon be mounting Knog flashers on my helmet since with my head moving around that will hopefully draw more attention than just another flasher. I've also got a lot of black-in-daylight Scotchlite tape since in daylight it blends in with my bikes black wheelrims, frame, seat (recumbent) and carbon tailbox. With all of this I'm going to make a bracket to attach pedal reflectors to my Speedplay pedals, which will render them single-sided but will mean I am legally compliant and as mentioned further up this thread will make me more visible as they are eye catching at night because they move.
From the description of your set up you come across as terrified to be hit.
I was the same when I first started cycle commuting, many years ago: I had a set up similar to your, was mainly using segregated routes with the odd unlit patch.
Yes, I was terrified to get hit on the few quiet streets I had to cycle on.
Eventually the fear passed, now I use 2 good back lights, in case one stops working, or gets detached from the bike.
One good front light on steady beam, a Sam Browne belt.
At times, I still feel invisible on the bike.
Worst bit is exiting the work's carpark, even the carpark attendant remarked on how many drivers blank me when I want to exit.
I don't think more lights would improve my visibility.
