So additional current for the PLI LEDs could be gotten by wiring the LEDs in parallel to the blade LEDs (again with the right resistor). That's as far as I've gotten in practice.
Whether you then have the individual PLI LEDs in parallel or series will in theory be a choice. LEDs are usually wired in parallel so if one fails it doesn't leave additional current load on the other LED(s) (putting them at risk). If the LEDs use different loads (perhaps true, if yours are different colours) then serial LEDs can have an imbalanced load, risking the weaker members of the herd. So a whole lot of parallel LEDs is perhaps more reliable, assuming you're running them at near their current maximum. Now whether that is best done with a whole lot of parallel resistors, or just one splitting to all LEDs (different calculations) I haven't seen any explanation of that.
